Voyaging: Nailing down when the first canoe pulled up on a Hawaiian beach.

 

Your grandfather might tell you otherwise, but it is increasingly clear that the first humans set foot in Hawai’i in the year AD 1000, give or take a few decades.

Archaeologists and other researchers have been honing on that period for a couple of decades as their tools have improved for determining the age of human-related activities and artifacts. Early, widely varying carbon-14 dates have been adjusted and refined, and several new technologies have been added to the tool kit.

This isn’t brand new information, but I still hear older Hawai’i people advocating for dates they remember being taught as little as 30 or 40 years ago.

Until and into the 1980s, the common assumption was that the Hawaiian Islands were first inhabited early in the first millennium after Christ, and a few folks still still argue for AD 500, 300 or occasionally even earlier.

In his seminal 1985 book Feathered Gods and Fishhooks, leading Pacific archaeologist Patrick Kirch reflected the wisdom of the period: “It is clear that colonization parties from the Marquesas were responsible for the settlement of Easter Island by about A.D. 400 and of Hawai’i by possibly by A.D. 300.”

But the science has improved much since then, and the errors of the early dating have been corrected. By the 2023 revision of Feathered Gods and Fishhooks, Kirch and Mark McCoy had moved the number to closer to 1000.

Why? Wrote the authors: “No one could have foreseen…the major technological advances that would come…the use of GPS and GIS in settlement archaeology, AMS radiocarbon dating and Bayesian modeling…high-precision dating of corals, stable isotope analysis of faunal remains or XRF geochemical analysis of stone artifacts.”

Professional archaeology now assumes there weren’t any humans in the eastern Pacific as early as CE 300 or 400. (Maybe a lost fisherman or an intrepid sailor who left no evidence.) It is more likely that Polynesian voyaging canoes around AD 900 began pushing—probably from the Samoa islands—into eastern Polynesia.

Why did those Polynesians voyage? There have been many theories, but one recent one is that they were driven out of their home islands by drought. David Sear and co-authors Melinda Allen, Jonathan Hassall and Emma Pearson said that drought may have lasted 200-400 years, certainly from before AD 900 to after 1100. 

Whether or not drought alone was enough to coerce people to abandon their homes, there’s an associated stressor. Population pressure would have been a big factor as expanding island families began outgrowing their small islands’ ability to feed them.

Science now generally presumes that on departure from the central Pacific islands, some of the eastern Pacific islands south of the Equator were populated first. Perhaps the Cook Islands, which are just to the southeast and downwind of Samoa. Then the nearby islands and finally then canoes came north to Hawai’i, east to Rapa Nui (Easter Island) and then west to Aotearoa (New Zealand.) The chronology could change with additional findings and new technologies.

But all of that voyaging may have occurred in a pulse of only a few generations. The voyaging canoes left Samoa around 900 and would have populated all those other islands within just a couple of hundred years.

“The archaeological and paleoenvironmental estimates of the colonization date show a striking convergence, indicating that initial settlement (of Hawai’i) occurred at A.D. 940–1130…and most probably between A.D. 1000 to 1100,” wrote pollen expert Stephen Athens and Timothy M. Rieth and Thomas S. Dye, in a 2017 article in the journal American Antiquity, entitled, “A Paleoenvironmental and Archaeological Model-Based Age Estimate for the Colonization of Hawai’i.” 

They cited updated radiocarbon dating and pollen from archaeological coring data.

One of the best resources for dating first human activity on Kaua’i was developed by David Burney and William “Pila” Kikuchi at Makauwahi Cave on the swampy south coast of the island. Their 2006 paper, based on flooded sediments in the cave floor, estimated first Polynesian activity at between AD 1039-1241. 

A lot of the earliest archaeological dates in Hawai'i are now settling in on that time period.

What is amazing, given the compressed period of Hawaiian occupation, is the extent of the great public works that were completed: the many hundreds of fishponds, the massive stone temples, the remarkable waterworks for flooded kalo fields and the vast dryland field agricultural systems.
