Plateau was retained to conduct a cultural resource survey prior to the construction of a communication tower overlooking the Walla Walla River valley in Umatilla County, Oregon.
According to the pre-field review, no previous cultural resource surveys have been conducted within the project area. However, a survey was performed within two miles of the project area where two rock cairns, an isolated find of five chert flakes, and an isolated find of a single chert flake were observed. These sites were not recommended for listing on the National Register of Historic Places (NRHP).
Plateau archaeologists Alexander New and Justin Hopt completed the cultural resource survey on July 19, 2016 in a manner consistent with Oregon State Law, and included inspection techniques to identify both surface and subsurface archaeological resources. Three probes were dug until bedrock was reached and no pre-contact or historic-era cultural materials or features were observed during the excavations. Plateau recommended that the proposed undertaking would result in no historic properties affected.
