The contract will cover ongoing curatorial services for a base year with four additional option years, ensuring the proper management and care of collections excavated from Corps lands, in compliance with various federal cultural resource laws. The Yakama Museum is uniquely qualified for this role due to its cultural expertise and established practices in managing Native American artifacts, which are critical for preserving the cultural heritage of the Yakama Nation.
