Proposed wetland restoration and flood control by the U.S. Army Corps of Engineers (Corps) associated with the north bank of the Salt River, near confluences of the Agua Fria and Gila rivers, requires the identification of cultural resources as laid out in Section 106 of the National Historic Preservation Act. The project area involves a wide, stable floodplain terrace below Frank Midvale’s Cashion Ruin. After the completion of a records search, archeologists from the Corps surveyed the project’s area of potential effects (approximately 700 acres) in the summer of 1999, identifying the historic St. Johns Canal (AZ T:11:93 [ASM]), and a possible Hohokam habitation site (AZ T:11:94 [ASM]). The historic canal is not eligible for listing in the National Register of Historic Places given its extensive modifications over time. The prehistoric site is potentially eligible for the National Register. The possibility exists for additional sites buried within the floodplain. In addition to National Register evaluations of the prehistoric site, subsurface exploration and geomorphic studies of the floodplain are proposed.
