Kohala is HOT!

Let’s get back to the HEAT. Archaeology on Pacific Islands can be wet or dry, but most of the time it is HOT– scorching, drill-your-brain HOT. This photo was taken from beneath our ubiquitous ‘shade tarps’, which we installed over excavation units in Leeward Kohala. Anna Browne-Ribeiro and I are extracting marine shell midden from a seiving screen in this photo. The ahupua’a (traditional land-division) of Kalala was rich with farmland and a rocky coast for fishing and collecting mollusks. We found the remains of 1000s of ancient meals embedded in the floors of Hawaiian houses. Malama ‘aina.

Lo’i

June 2006, my students conducted an archaeological excavation of the Upper Halawa lo’i. A lo’i is made by constructing a set of terraces, either of stone or of earth, which is used to pond water across a broad area. Kalo (taro, Colocasia esculenta) can grow in dry soil, but it produces larger, juicier corms if it is planted in shallow water that can slowly drain, bringing in nutrients and oxygen. We excavated beneath the walls of the lo’i of Upper Halawa in order to collect tiny flecks of charcoal, which were deposited when the land was cleared and the lo’i was constructed. In that way, we can determine the age, using radiocarbon dating, of the installation of the lo’i. Malama ‘aina.

Upper Halawa

Upper Halawa gulch, in windward Kohala. Several sets of loi were constructed in this gulch approximately 400 years ago, and back then this place would have been sunny and open, with nodding beds of taro leaves in every corner. Today this narrow gulch is shaded by a creaking forest of shaggy-barked eucalyptus, and its floor is a fragrant nest of ginger flowers. Malama ‘aina.

Pololu

The black beach of Pololu valley may have been one of the first places colonized by Hawaiians. Located on the windward side of Kohala, the valley is wide and deep, with a high series of hanging valleys at its back. In 2006 Michael Graves and I began a project to investigate the archaeological collections of Pololu, which had been generated in the 1970s by a series of field schools directed by Dave Tuggle. Their excavations revealed deep deposits in the sand dunes at the mouth of the valley, at the base of which were a series of fire hearths that were packed with twisted and burned fibers. After sitting in a jelly jar for over 30 years, Gail Murikami identified the fibers to be native fern, hapu’u. I submitted a sample for radiocarbon dating, which revealed that the ferns were burned between AD 1259-1390. Pololu is an old place that was once filled with people, but is now a wild place, with quiet groves of invasive guava mixed between abandoned terraces that were once used for growing taro.

Pueo

In Kohala we got up early, usually around 5 am, so we could be in the field by 6:30. Pueo, the Hawaiian owl (Asio flammeus sandwichensis) would sometimes be waiting for us on a distant fencepost, watching the grass for scurrying rodents that were startled by our jeep. Pueo are becoming a rare sight in Hawaii, as light pollution disrupts their twilight hunts, and predators like introduced rats and cats destroy chicks and eggs in the nest. I treasure the memories of seeing them glide soundlessly overhead; it was a beautiful way to start each amazing day. Mahalo. Aloha ‘aina.

Winds of Kohala

Aloha kakou. Archaeology in Kohala is always windy- your ears burn, your eyes stream, and you end up with dirt packed into every crack of your body and clothing. The winds in Kohala even have names, depending upon when and from where they blow. Sweet Kris (hair-in-my-face) and Jillian Swift (the coalminer, aka @swiftasafox ) are in this picture from 2009, excavating a platform that was once the foundation of an ancient Hawaiian farmhouse. Aloha ‘aina.

Kohala Field System

Aloha kakou. As winter takes Ohio it’s time to pull some older photos down from the rack. This view is of the Kohala Field System, one of the most expansive pre-historic agricultural features in the world. It’s located on the windy western slopes of the Kohala peninsula, on Hawai’i Island. Hawaiians constructed miles of wind-breaks in order to shelter their sweet-potato plants, and between AD 1300 and the contact period the region produced a bounty of crops. This view was taken from the top of Pu’u Kahena, a cinder cone that overlooks the central part of the field system. One of the most beautiful places that I’ve had the privilege to explore and research. Aloha ‘aina.

Back from the Darkness…

In May of 2017 I directed the final season of fieldwork (at least for now) in the Naqalimare region of the Sigatoka Valley, Fiji. This time we investigated the deposits inside Naihehe Cave.  Kyle Riordan (OSU Graduate Student in Anthropology) led the excavation of two test units in the cave, and collected samples for the analysis of sediment origin, deposition, and structure.  Excavations in Fiji were followed by two weeks of analysis at Idaho State University’s CAMAS lab, where Kyle directed the analysis of the sediments using elemental scanning microscopy.  Analyses at OSU’s laboratories are still ongoing– radiocarbon dates for charcoal layers discovered in the cave are coming soon!

It’s sabbatical time!

As of August 2016, I am on a one-year sabbatical.  I have dedicated the year to completing two manuscripts:  a textbook, co-authored with Dr. Joy McCorriston, dedicated to understanding world prehistory within the context of the Anthropocene, and a book focused on the prehistory, ecology, and recent history of the Fiji Islands.  That book is tentatively entitled, ‘Three Thousand Years in the Southwest Pacific’.  During the year I will be writing as much as possible from a quiet and cozy home in Port Ludlow, Washington.raven returns as salmonRaven returns as salmon, at the Jefferson County Library, Port Hadlock, Washington.
