In 2008, the land went up for sale, and the archeology department at Central Washington State University (CWU) was contacted to investigate this find, initially believed to be in wind blown loess deposits, similar to the Wenas Creek mammoth.

In May of 2008, a pedestrian survey (led by Bax Barton and Jake Shapely, and conducted by CWU and Kamiakin High School students) quickly found trace evidence (e.g. tooth enamel) that led the investigators to a suspected location of additional remains.


Follow up excavations over the next two days uncovered a number of mammoth size bones, confirming the presence of a relatively well preserved and potentially complete skeleton.


Test excavations found multiple skeletal elements, including ribs, and a humerus (upper arm bone).


Geologic reconnaissance of the site indicated the mammoth bones were hosted in Ice Age flood deposits.

The site’s location on the edge of Coyote Canyon, gave rise to the site’s name.
