Fivemile Wash Survey

The Fivemile Wash survey was conducted in compliance with the Bureau of Land Management’s responsibilities under Section 110 [a][2][A] of the National Historic Preservation Act (16 U.S.C. 470). Eight sites were located in 1,195 acres centered on a 2.6-mile-long section of the wash located between the Colorado River floodplain and the Black Mountains in Mohave County, Arizona. Seven of the sites are aboriginal/prehistoric lithic scatters, exhibiting early-stage reduction of choice lithic materials found among cobble and gravel deposits along the wash. A 1/4-mile-section of historic Route 66 was also documented. The eligibility of all sites for inclusion in the National Register of Historic Places was evaluated.
