Report on Archaeological Survey of Bureau of Reclamation Lands Along the Middle Gila River Near Cochran and Winkelman

This is the final report of the Cochran Survey project. The draft report can be found at the following link: https://core.tdar.org/document/393912 The Cochran Survey was administered over a period of 25 months, beginning in April 1998 and ending in May 2000. As funding became available delivery orders were submitted from the Bureau of Reclamation (Reclamation) to Archaeological Consulting Services (ACS) to increase the survey coverage under their Section 110 mandate. Initially, the survey included portions of the USGS 7.5' North Butte and Grayback quadrangles near the historic site of Cochran, and was later expanded to include a second area of non-contiguous parcels near the towns of Hayden and Winkelman, all in the Gila, and Salt River Baseline and Meridian, Pinal County, Arizona. For the purposes of organization, the two areas are referred to below as the Cochran unit and the Winkelman unit.本文件为科克伦调查（Cochran Survey）项目的最终报告。该报告的草案版本可通过以下链接获取：https://core.tdar.org/document/393912。 科克伦调查的实施周期为25个月，自1998年4月启动，至2000年5月结束。因后续获得专项资金，美国垦务局（Bureau of Reclamation，简称Reclamation）向考古咨询服务公司（Archaeological Consulting Services，简称ACS）下达了交付订单，以扩大其依据《第110条》授权职责所覆盖的考古调查范围。 项目初期，调查范围覆盖了位于科克伦历史遗址附近的美国地质调查局（USGS）7.5分幅北巴特（North Butte）与格雷巴克（Grayback）地形图幅的部分区域；后续又将范围扩展至亚利桑那州皮纳尔县希拉河与盐河基准线及子午线区域内、海登（Hayden）镇和温克尔曼（Winkelman）镇附近的另一处非连片地块区域。为便于统筹管理，下文将这两个调查区域分别称为科克伦片区与温克尔曼片区。
