The Sun Rises at Six on Nikumaroro, Every Day

By Joe Cerniglia

[TFK's Preface: Another contribution by Joe, whose careful analyses of artifacts from the Nikumaroro village and Seven Site contribute importantly to our work, Thanks, Joe!]

On July 5, 2017, during the second “In Search of Amelia Earhart” trip to Nikumaroro, organized by Betchart Expeditions, archaeologist Dr. Richard Pettigrew spotted the square movement of a small alarm clock on the surface of the ground among other artifacts near the old village dispensary.[1]

The clock movement, measuring 2 15/32” X 2 5/32” X 15/16”, appears to have been resting within the perimeter of one of the village households. The outer casing is entirely missing. The movement itself is warped, bent and corroded as well as oxidized in spots with a rust-like coating.

Based on the distinctive design of the plates, as well as the dimensions and layout of the movement, clock expert Bill Stoddard, owner of Bill's Clockworks in Flora, Indiana (, has identified the artifact as an example of a Westclox movement #66.[2]  This movement, according to Mr. Stoddard, "was used in many of the less expensive windup alarm clocks such as Bingo, Spur and Bantam (to name a few) from the early 1930s through the 1960s."

The clock movement is inscribed "3 54" on the northwest quadrant of the exterior of the rear-facing plate, indicating it was manufactured in March of 1954, 17 years after the 1937 world flight of Amelia Earhart and Fred Noonan. No other letters or numbers are visible on the movement.

Mr. Stoddard, working with Gary Biolchini, author of Westclox: An Identification and Price Guide (, determined that Westclox clocks manufactured in Scotland have the most features in common with the Nikumaroro clock. This determination was made primarily on the basis of the location and orientation of the date stamp. The artifact has the date stamp on the exterior of the rear plate. Only clock movements from two of the Westclox factories' clocks were found to have this configuration. One of these movements was from Canada, but all Canadian Westclox clocks located so far have the inscription upside-down, relative to the clock face, and say “MADE IN CANADA” on their movements. Some, but not all Scottish Westclox clocks, say “MADE IN SCOTLAND” on their movements. The only one thus far identified that does not display this inscription has “UK” inscribed to the right of the date stamp. The Nikumaroro clock movement has no inscription other than the date, yet it still shares more attributes with the movements from Scotland than with those from other countries.[3]

Image 8: Inscription of the Scottish Westclox clock movement is on left; inscription of the Nikumaroro clock is on the right.

The material composition of the clock movement is unknown but may be a combination of aluminum and steel. Westclox movements from the 1950s, as the artifact is, sometimes were made of steel gears and aluminum plates.[4]

It would seem incredible that the island of Nikumaroro was at one time in the market for American clocks made in Scotland, but research of the circumstances and needs of the island coconut plantation, active from 1939 to 1963, and of the supply routes of Westclox, amply support the existence of this market.

In September 1953, the only clock factory in all Australia, Westclox Pty. Ltd. of Melbourne, closed its doors due to rising labor costs. A news story about the closure reported optimistically that imported clocks would be cheaper than those that had been made in the shuttered factory.[5]

Even before Westclox of Melbourne ceased operations, imported Westclox clocks from Scotland appear to have been common and desirable in the Pacific region. In June 1949, Pacific Islands Monthly, the premier and perhaps only news outlet for islands such as Nikumaroro, announced exchange rates were favorable when buying imported Westclox clocks from the newly opened clock factory in Strathleven, Dumbarton, Scotland. Details could be obtained by writing to the Pacific Islands Trading Co. address in San Francisco.

In March 1950, the same Pacific Islands Trading Co. that was a wholesaler of Scottish Westclox clocks purchased a half-page Westclox advertisement in Pacific Islands Monthly.

Clocks were selling in the Pacific, and there is evidence that timekeeping was important to the Nikumaroro colony as well. Lands Commissioner Paul Laxton visited Nikumaroro in 1951 and wrote a detailed report of the island and its inhabitants for the Journal of the Polynesian Society.[6] In his article, he tells of the role that clocks played in the life of the colony, and how these clocks were adapted to the island's purposes:

"The sun rises at precisely six every morning at Nikumaroro, year in and year out. We could not understand this at first for the island is appreciably south of the equator, until we found that at sunrise the island clocks are set at six. Our own watches, at zone time, did not correlate very well with this, while the radio shack meanly observed Greenwich time. After a few weeks Nikumaroro won and we lived by the sun."

We lack the detailed records to substantiate that the island colony specifically purchased a 1954 Westclox clock made in Scotland, but based on Laxton's account and on what has been documented in advertisements and news articles, it seems entirely possible and even likely.

A clock on the island in 1954 makes perfect sense from the standpoint of Nikumaroro's history. The clock was made only three years after Paul Laxton had resolved that a steely discipline instilled in the villagers would be needed for the colony to survive after years of British distraction with World War II and the village’s extended mourning over the death of Gerald Gallagher, the island's first commissioner. The clock, if not Amelia Earhart’s, is still an artifact with its own fascinating history, symbolizing Nikumaroro's last attempt at righting itself and becoming a going concern. Time really was of the essence, but it was running out. Nine years after this clock was made, the colony would falter, this time for all time. Nikumaroro's residents would repair to the Solomon Islands for what they hoped would be a new and better life, leaving behind a remnant of their efforts to be industrious, and on time every morning at “six o’clock.”

Bringing “Amelia Earhart UNRESCUED” to the Silver Screen

Now that my novel, Amelia Earhart UNRESCUED, is in bookstores everywhere, it’s obviously time to think seriously about a screen adaptation.  Here’s why:

1.       It’s widely known that Hollywood (maybe not Bollywood) is hard up for new stories – hence the constant reworks, reboots, retreads of old movies and TV series. UNRESCUED is a new story – albeit derived from an old and famous one.

2.       UNRESCUED is highly cinematic – beautiful island, beautiful star (auditions, anyone?), an elegant, doomed airplane, a shipwreck, a massive storm, the vast Pacific, challenging animal characters.

3.       Speaking of the last, imagine the potential for computer-generated imagery (CGI) as applied to the wisecracking crab, the psychotherapist booby, and the ghost.  And what stars can provide their voices?

4.       And ultimately UNRESCUED is a story about accepting and transcending one’s fate, which may provide the inspiration we all need in these strange, strange times.

Amelia Earhart UNRESCUED

My second novel, Amelia Earhart UNRESCUED, will soon be in bookstores. A prequel to my 2009 Thirteen Bones, it imagines Amelia Earhart's (AE's) fate from the time of her hypothesized landing on Nikumaroro with Fred Noonan to the time of her passing. It incorporates and is consistent with all our historical, archaeological, osteological, radio, and other data, though I've not interpreted all those data quite as some of my colleagues have, and I've imagined quite a lot. Talking (multilingual) crabs, a psychotherapist booby, the island's resident spirit-being, and of course AE's state of mind as she loses her airplane, loses Fred, struggles with the environment and gradually succumbs. Not an entirely pretty picture, but a respectful one, I hope, and one that's as close to what probably really happened as I could make it.

AE UNRESCUED is published by Flat Hammock Press of Mystic, CT ( Royalties, if any, will be divided evenly among the Phoenix Islands Protected Area, the Amelia Earhart Birthplace Museum, TIGHAR, and me. Although publication is a couple of months off, I can make galley pages available to interested reviewers; contact me at

I'm grateful to everyone who helped bring AE UNRESCUED to publication, but let me particularly thank Janis Carty for the cover art, and for putting up with my suggestions. And of course I'm grateful to TIGHAR for making it all possible.

The Archaeological Context of the Human Bones Found on Nikumaroro in 1940

Richard Jantz's re-analysis of the measurements taken in 1941 on human bones from Nikumaroro, recently published in the journal Forensic Anthropology*. has attracted a good deal of media attention, as well it should. Unfortunately, however, the measurements are being taken by the press as though they comprise the only evidence that Earhart and Noonan wound up on the island. 

My 2012 paper, "Amelia Earhart on Nikumaroro: a Summary of the Evidence"** outlines the general arguments and data underlying the Nikumaroro Hypothesis. The following paper, published in the February 2018 issue of TIGHAR Tracks along with a reprint of Jantz's paper and a critique of the 1941 analysis by Ric Gillespie, focuses on the specific site where all available evidence suggests that the bones were discovered.

The Archaeological Context of the 1940 Nikumaroro Bones Discovery
Thomas F. King[1]
November, 2017


In 1940, colonists on Nikumaroro Atoll in the Phoenix Islands discovered a human cranium on the southeast end of the island. They buried the cranium, but Gerald Gallagher, Administrator of the Phoenix Islands Settlement Scheme under which the island was being prepared for settlement, became aware of the discovery and recovered twelve additional bones[2] and various artifacts, which he sent (along with the cranium, which he had excavated) to the headquarters of the Western Pacific High Commission (WPHC) in Fiji. The bones and artifacts all went missing during World War II, but not before the bones had been measured and commented upon by Dr. David Hoodless, then Principal of the Central Medical School for the Colony of Fiji.  Correspondence and internal WPHC memoranda about the bones discovery (which we colloquially refer to as “the bones papers”) were discovered in 1997 in the Kiribati National Archives by historian Peter MacQuarrie, and substantially augmented by TIGHAR discoveries in the WPHC archives then on file at Hanslope Park in England[3].

In a 1998 paper, physical anthropologists Karen Burns and Richard Jantz, with input from Richard Gillespie and me, concluded that the bones discovered in 1940 may quite likely have been those of Amelia Earhart[4]. In a 2015 paper[5], Pamela Cross and Richard Wright have dismissed this conclusion.

Richard Jantz has prepared a response to the anthropological assertions in the Cross/Wright paper ( Ric Gillespie has written an analysis of the 1940/41 British investigation and some of the assertions made by Cross and Wright (See TIGHAR Tracks 34:1, February 2018. The purpose of the paper presented here is to outline the archaeological background to Gillespie’s and Jantz’s discussions.

Where Were the Bones Found?

Gallagher’s 17th October 1940 telegram reports that the bones were found “on South East corner of island,” under a “ren” tree[6] (Tournefortia argentia.). His reports provide no further detail other than distance from the high tide line, but he was directed to make an “organised search” of the area. A 1941 U.S. Navy airphoto shows that vegetation had been cleared near the island’s southeast end – an activity that would most likely be a necessary part of what Gallagher described as an intensive search[7] – adjacent to an unvegetated linear feature shaped like the numeral seven. This feature is stable, appearing in multiple aerial and satellite images through the years. This made the location imaged in 1941 fairly easy to find.

In 1996 TIGHAR researchers performed an initial survey of the site, which we call the “Seven Site” because of the adjacent natural clearing. Noting only bird bones, a hole in the ground, and surface artifacts easily attributable to the 1939-63 colonists and the 1944-46 Coast Guardsmen, TIGHAR did no further work there at the time.

Some months later, in 1997, historian Peter McQuarrie found the documents surrounding the 1940 bones discovery; this, of course, drew our attention back to the Seven Site, leading to four episodes of archaeological work there. In 2017, forensic dogs alerted on the ground under a fallen Ren tree (See below) and nowhere else in the vicinity[8], strongly suggesting that the tree we call “the Big Ren,” or a previous tree at the same location, was the site of the bones discovery.

Artifacts Associated with the Bones

Statements by Gallagher, Dr. K.R. Steenson and others in the bones papers[9] indicate that the following artifacts were found in association with the bones:

·         A Benedictine bottle;
·         Parts of a woman’s and man’s shoes;
·         Small corks on chains;
·         Part of a sextant’s inverting eyepiece; and
·         A sextant box, wooden, with dovetailed corners, inscribed with the numbers 3500 and 1542.

All of these artifacts have been lost, and none is documented as having received much attention by the WPHC, with the exception of the sextant box.

The sextant box was examined by Cdr. G.B. Nasmyth and Harold Gatty, the latter a world famous aerial navigator then organizing commercial aviation operations in the Pacific. Gatty thought the box was English and had most recently been used simply as a container. Gallagher had identified the box as being for an “old fashioned” sextant “probably painted over with black enamel.” Perhaps because celestial observations from aircraft were made using a bubble octant rather than an old fashioned mariner’s sextant, Gatty opined that the box would not have contained an instrument used in trans-oceanic aeronautical navigation[10]. Although Gallagher reported the box to be marked with numbers, Nasmyth noted “no distinguishing marks” and said only that the dovetailed corners suggested French origin.

TIGHAR research into the numbers on the sextant box leave little doubt that it was for a Navy Surveying Sextant manufactured by Brandis & Sons of Brooklyn, New York. The 3500 is apparently the maker's number, while the 1542 was likely inscribed on the instrument and noted on its box when it was inspected at the U.S. Naval Observatory. Brandis boxes have dovetailed corners. A large number of Brandis sextants were acquired by the U.S. Navy toward the end of World War I, and disposed of as surplus thereafter. Some were modified for aeronautical use. Earhart’s navigator, Fred Noonan, reportedly used a nautical sextant as a “preventer” (back-up) instrument when navigating for Pan American on its Pacific routes, and a photo of the navigation room in a Pan Am Clipper on which Noonan served shows a Brandis sextant box.[11].

Archaeological and Oral Historical Work Pertaining to the Seven Site

 In 1996, 2001, 2007, 2010 and 2017 we conducted archaeological surface survey and excavations at the Seven Site. In 2011 a TIGHAR team visited veterans of the Nikumaroro colony now living in the Solomon Islands and collected oral historical information on uses of the site. A comprehensive report on Seven Site archaeology is in preparation.

Summary of Research Results to Date

In summary, there is archaeological and oral historical evidence of human activity at the site during four time periods:

1.   Before 1940, when a castaway may have lived and died there;

2.   In 1940-41, when Gallagher and the colonists searched the site, likely in the context of logging its valuable Kanawa (Cordia subcordata) hardwood and preparing the site for coconut planting;

3.   In 1944-46, when U.S. Coast Guardsmen from the nearby long range radio navigation (LORAN) station appear to have hunted birds and conducted target practice at and around the site; and

4.   Sporadically from around 1941 through the 1950s, when the area was cleared and planted in coconuts, and young men from the colonial village occasionally camped there while hunting birds and turtles.

These sequential activities have created a complicated archaeological record, made more difficult to interpret by the fact that there is virtually no soil at the Seven Site within which stratigraphy can develop. Almost everything from all four phases of human activity occurs in the uppermost ten centimeters of the coral rubble that makes up the site.

Analysis of the Seven Site is not yet complete[12], but we can say the following with some confidence about the pre-1940 “castaway” period:

Someone ignited and maintained four substantial campfires, presumably in sequence, scattered over an area of about 1100 square meters. There are other smaller, more ephemeral campfire sites that we think most likely reflect episodic use of the site during the 1941-63 period.

The four major campfire sites contain varying quantities of fish, bird, and turtle bones.

The fish bones appear to represent an unselected sample of reef species, suggesting to us that the camper was catching whatever he or she could catch – unlike what could be expected of island people with greater knowledge of the reef. The camper apparently removed the fish heads before cooking, unlike island people who value and consume fish heads (Jones 2011). 

The bird bones represent species readily available on and around the Seven Site – boobies and frigate birds (Collins 2011). Whoever caught them apparently skinned them – a behavior reported by colonial veterans in the Solomon Islands but also employed in preparing fowl in the United States[13].

Turtle bones include parts of the carapace and plastron, probably representing  one adult sea turtle (Hutchison 2011), and long bones from several infantile turtles (Jones 2011). Island people on the whole do not eat baby turtles.

The Seven Site also contained two ca. 2m2 concentrations of Tridacna sp. (“giant”) clam shells, one representing seventeen clams, the other nineteen[14]. In one deposit, adjacent to a campfire feature, the valves are undamaged, as though they were opened simply by exposing them to heat. In the other, the “lips” of several valves are damaged, apparently by the forceful insertion of a small wedge found nearby, fashioned from the rim of a steel barrel. Some have been smashed open with rocks. This is very atypical of island people, who know how to harvest Tridacna clams by quickly cutting their adductor muscles while they are filter-feeding in the lagoon or on the reef, then cutting out the meat and leaving the valves behind. If they do bring a complete Tridacna ashore, they know that simple exposure to the heat of the sun or a fire will cause its valves to open.

We recovered (or recorded and left in place) a diverse range of artifacts at the Seven Site. The most prominent were many sheets of corrugated iron, rusted into tiny pieces, which we think were associated either with clearing the site in 1940-41 (perhaps for skidding logs down to the lagoon) or with post-war development of the site for coconuts. The most common artifacts are cartridges and occasional spent slugs from M-1 carbines, carried by the U.S. Coast Guardsmen. A few .22 caliber rounds were found, perhaps from a pistol that Gallagher is recorded as having owned. Most interesting from the standpoint of identifying the castaway who presumably lived and died at the site are:

·         Two broken, partially melted bottles apparently dating to before World War II, found in one of the campfire features, which appear to have shattered while standing upright in the fire; we suspect that they represent an attempt to boil water. One bottle was most likely made to contain St. Joseph Liniment or St. Joseph Penetro (cough syrup) while the other was a returnable U.S. beer bottle probably manufactured prior to World War II[15].

·         In the same campfire feature, both halves of a snap fastener consistent with those on a Burroughs Wellcome & Co. wooden “Tabloid” first aid kit; a “Tabloid” kit is documented to have been aboard Earhart’s Electra on the first World Flight[16].

·         Two adjoining fragments of a piece of thin beveled glass, almost certainly from a mirror, several fragments of red material chemically consistent with early 20th century rouge, and some tiny fragments of ferrous metal, all of which we interpret as the collective remains of a woman’s compact, similar in shape and size to an object shown in Earhart’s hands in two contemporary photographs (See King 2012);

·         A small footed jar that contained a mercury-based product, similar to jars containing mercury-based ointment used in the early 20th century to fade freckles (Earhart had freckles)(See Cerniglia et al n.d.);

·         A fragment of a Mennen bottle, probably once containing skin lotion;
·         The base of a skin or hair lotion bottle whose base code indicates it was manufactured by Owens-Illinois at Plant 14 in Bridgeton, New Jersey (See Cerniglia 2012);

·         A bone-handled, double-bladed jackknife, manufactured by the Imperial Cutlery Company of Providence, Rhode Island sometime between 1930 and 1945, apparently disassembled to remove the blades, possibly for use in fashioning a spear[17]. A similar but not identical knife is recorded as having been aboard Earhart’s Electra after its accident in Hawaii during the first World Flight attempt;

·         A zipper pull, made by the U.S. based Talon company and reliably dated to not earlier than 1933 and not later than 1936[18]; Earhart wore zippered slacks, and carried at least one zippered bag in the Electra; and

·         A tiny piece of aluminum foil with lettering on it that, while sparse, is consistent with that of an American signal torch, and whose unmarked side exhibits traces of sulfur (67%), silicon, zinc and iron consistent with flammable black powder.

Other artifacts, such as several leads for a mechanical pencil, what may be the remains of a hair-curling iron, the probable remnants of a flashlight battery, and many, many tiny fragments of thin ferrous metal, remain in analysis.

Finally, in 2010 we recovered a single phalanx (finger/toe bone) from a spot under the Big Ren.  The University of Oklahoma DNA laboratory was unable to extract usable DNA for analysis in 2010, so at present even species identification is uncertain. It could have been the phalanx of a sea turtle (though we have found no other adult sea turtle bones at the Seven Site other than those of the carapace and plastron) or of a dolphin (though we have found no other dolphin bones at the site). This bone is currently awaiting further analysis.

In 2015 Dawn Johnson retrieved samples of the coral rubble “soil” at the base of the Big Ren. These were subjected to controlled inspection by highly trained forensic dogs employed by the Institute for Canine Forensics (ICF)[19]. Dogs alerted on two of the samples, indicating that they sensed an association with human remains. This fortified our impression that the area around the Big Ren is where the bones were found in 1940, and helped motivate the National Geographic Society to support the 2017 work in which ICF canines alerted repeatedly under the Big Ren. Soil samples from alert sites are currently under analysis.

Of course, there are multiple ways to account for the artifacts, bones, shells and fire features that make up the Seven Site, but one of the more efficient plausible hypotheses is that a woman from the United States lived and died there in the late 1930s, after which several other uses of the site complicated the evidence left by her presence and passing.
