UAF ridge now carries Troth Yeddha' name

The ridge along which the University of Alaska Fairbanks is built now officially carries the name Troth Yeddha', or Indian Potato Ridge.

The name was approved Feb. 14, 2013, by the U.S. Board on Geographic Names. The ridge previously had no official name. [link to official GNIS entry]

Troth Yeddha' wins commission's approval

On November 26, 2012, the Alaska Historical Commission, which reviews proposals to name physical features in the state, voted unanimously to approve Troth Yeddha' as the name for the ridge on the UAF campus. It has had no official name up to now.

About the name Troth Yeddha'



Robert Charlie discusses the significance of the name Troth Yeddha' (Oct 2011)


The land now occupied by the University of Alaska Fairbanks campus was called Troth Yeddha' (sometimes spelled Troth Yedda' or Troth Yeddh) by the Lower Tanana Athabascans. Lower Tanana is the indigenous language of the Lower Tanana Valley, spoken east-to-west from Moose Creek Bluff (past North Pole) to Baker Creek/Zitziana River. Some of the main Lower Tanana village sites are  Chena Village (Ch'eno' Khwdochaget),  Nenana (Toghotili), Old Minto (Menhti Khwghotthit), and Toklat (Tu Tl’ot Khwdochaget).

The word troth refers to the plant known in English as "Indian potato", "wild potato", or "wild carrot" (Hedysarum alpinum). The word yeddha' means "its ridge, its hill." Linguistically, it can be analyzed as the word yetth "ridge" plus the possessive suffix -a' (the change from tth to ddh in the possessed form is part of a regular phonological process). Thus the name Troth Yeddha' can be literally translated into English as "Wild Potato Ridge." The apostrophe at the end of the word yeddha' is a meaningful symbol that represents a glottal stop in the Tanana language.

Other areas now on and around the UAF campus also have original Athabascan names. Some examples include:

  • Ch'eno' Chena River
  • Sresr Ddhela' Ester Dome (literally: 'black bear mountain')
  • Tr'ekhwghodegi Troth Yeddha' Bena' Smith Lake
    (literally: 'upper wild potato ridge lake')
  • Tr'ekhwghotthidi Troth Yeddha' Bena' Ballaine Lake
    (literally: 'lower wild potato ridge lake')

Various archaeological, linguistic, and oral history records indicate the importance of Troth Yeddha' to the Athabascan people. There is evidence of small a settlement at Troth Yeddha' prior to the 1840s. Troth can still be found in steam beds and flood plains between the university and the Tanana River. The roots of troth are the most important vegetable food for the Alaska Athabascans.

A description of troth harvesting by the Chena people, very likely in the lowlands south of Troth Yeddha’, was given by Laura Anderson, the last Chena speaker, in her classic woman’s narrative According to Mama (1956:14, reprinted in 2011 by St. Matthews Episcopal Church):

Sometimes women went poking a long pole in the ground all over. When the ground felt just right there was a mice nest. This nest they dug up and there was a cache of Indian potato roots as big as a big basket sometimes. The women put this in a basket and ate it. The mice got nothing!  This Indian potato root people dug, too, and buried it just in dirt. In the middle of winter it had turned just sweet and women peeled off the skin and cooked the white inside root. They would get bear grease boiling and then put the root in.

“Mama,” was Helen David Charley (1862-1957). The fascinating factual summaries in the book are the earliest first-hand accounts of aboriginal life in the Fairbanks area.

The usage of troth is described by Father Jules Jetté in the Koyukon Athabaskan Dictionary:

The [troth] is good only during the winter, when the natives gather it, digging for it under the snow. It is then round and full, juicy and tender. After the thaw it loses its qualities, becomes hard, woody, and tasteless. It is also used as a substitute for tea or coffee. For this purpose, the root is sliced transversely in segments 1 to 2 inches long; these are divided longitudinally, by separating the fibers, and these are cut again across in small portions, which are afterwards dried and roasted in a frying pan. They are used as tea, in an infusion, and sometimes as a decoction. The beverage thus prepared is said to taste like chocolate. (Jones and Jetté 2000)

A Tanana Valley War Story

The name Troth Yeddha' features prominently in a story related by Hester Evan. In this important piece of oral history, Hester describes a raid on a small village at 'Indian Potato Hill'. This raid took place in about 1843; there were casualties, and there were three survivors. The story was recorded by James Kari on February 15, 2001, on the University of Alaska campus at the Troth Yeddha' site. Hester uses her own Toklat dialect, pronouncing the place name as Tsoł Teya', but it is nonetheless the same place. This story, powerfully told, clearly speaks to the long history of occupation of Tanana Valley by the Lower Tanana Athabascan peoples.

A transcript of Hester Evan's story can be downloaded here.
