Cultural Resource Site Assessments for Collom Expansion Project CotoNyo
NRHP Status and Condition Assessment
In 2005 TRC recommended the prehistoric portion of site 5MF.6098 as needing additional data
to determine its eligibility for inclusion on the NRHP. The historic portion of the site is
recommended as not eligible for inclusion on the NRHP under any potential criteria. Tetra Tech
concurs with this recommendation. The only observed impacts were to the historic component
and consist of deterioration common to abandoned historic era habitation sites. The historic
component is not eligible for inclusion on the NRHP and the impacts have no effect to the overall
site.
5MF.6116 — Rock Cairn, Needs Data
Site 5MF.6116 was originally recorded in 2005 by TRC as part of the Colowyo Collom Mine
expansion project. The site is reported as a collapsed rock cairn consisting of approximately 50
unshaped tabular sandstone slabs. The collapsed cairn covers an area of about 2 m by 1 m in
size. No artifacts or other evidence to suggest temporal or cultural affiliation were recorded in
association with the cairn. In 2015 Tetra Tech revisited the site as part of the current undertaking
(Figure 22). The cairn appears to be in identical condition as when it was originally recorded in
2005 with no new findings observed at the site. Only notable changes are continued sagebrush
growth, but the growth has not adversely impacted the cairn.
NRHP Status and Condition Assessment
In 2005 TRC determined that site 5MF.6116 required additional data to determine if the site should
be included on the NRHP. Additionally, consultation with recognized Native American tribes was
recommended. Tetra Tech concurs with these recommendations. The only noticeable impact to
the site appears to be sagebrush growth. Otherwise the site remains in the same condition
reported in 2005.
5MF.6128 — Historic Homestead and Artifact Scatter, Eligible under Criterion A
Site 5MF.6128 was originally recorded in 2005 by TRC as part of the Colowyo Collom Mine
expansion project. The site is reported to consist of a historic homestead with five features
(Features 1 through 5) and three artifact concentrations. Feature 1 is the foundation remains of a
residential building with a dense artifact concentration of glass and ceramic just east of the
feature. Feature 2 is a rectangular foundation cut into the lower slope of the ridge along the
eastern edge of the site. Feature 3 is a single room dugout also built into the side of the slope.
Feature 4 is a roughly square earthen depression. Feature 5 is portions of a sandstone foundation
roughly rectangular in shape. The artifact assemblage among the concentrations is comprised of
mostly cans, glass and dinnerware fragments with miscellaneous items including tin pots, kettles,
a spoon, and various metal debris.
In 2015 Tetra Tech revisited the site as part of the current undertaking (Figure 23). The five
features were located along with the artifacts concentrations of cans, glass, rusted metal debris
and wire. Each feature is in the same condition as originally reported with no significant changes
observed. The most significant observed impact to the site is livestock grazing. Feature 1 is
surrounded by trees and near Collom Creek. The nearby water and available shade creates an
environment that livestock like to regularly congregate. The area has significant abundance of
manure, wallowing pits, and hoof prints, Historic artifacts in this part of the site have been
subjected to significant trampling and scattering by the livestock. However, the impacts have not
significantly degraded the overall condition of the site.
