Appraisal of the Archeological and Paleontological Resources of the Moorhead Reservoir, Montana and Wyoming, Supplement

This report has been prepared by the Missouri River Basin Survey, Smithsonian Institution, for, and at the request of, the River Basin Recreation Survey, Region Two Office, National Park Service, in accordance with a Memorandum of Understanding between the Smithsonian Institution and the National Park Service, approved October 9, 1945* It is based upon two archeological surveys — the first in June 1949 by a two man party supervised by Richard P, Wheeler and the other from September 5 to October 6, 1950 by a two-man party led by Robert L, Shalkop — and a paleontological survey carried out in July 1947 by Theodore E. White and an assistant. The results of the first archeological survey and of the paleontological survey have been previously reported; they are summarized in this report, together with the results of the later archeological survey,

Although the archeological remains discovered in the Moorhead Reservoir area are not spectacular, the 18 sites recorded are sufficient evidence of extensive aboriginal utilization of this region to indicate the necessity for some exploratory excavation. Two sites -- 24PR8 and 48CA6 — appear to have been occupied more intensively than the others and it Is these to which attention should be first directed. It is estimated that 0,1 excavation unit5 will be required for the adequate investigation of each of these sites, Since previous experience in those reservoirs in the western part of the Plains which contain archeological remains has demonstrated that intensive investigation almost

本报告由史密森学会（Smithsonian Institution）密苏里河流域调查项目组编制，为国家公园管理局（National Park Service）第二区域办公室流域休闲调查项目服务并受其委托，依据双方于1945年10月9日批准的《谅解备忘录》*完成。本报告基于两项考古调查与一项古生物学调查：第一项为1949年6月由理查德·P·惠勒（Richard P. Wheeler）督导的两人工作组实施；第二项为1950年9月5日至10月6日由罗伯特·L·沙尔科普（Robert L. Shalkop）牵头的两人工作组开展；古生物学调查则由西奥多·E·怀特（Theodore E. White）及其助手于1947年7月完成。第一项考古调查与古生物学调查的成果已先期发表，本报告将对前述两项成果进行综述，并纳入后续第二项考古调查的研究结果。尽管在穆尔黑德水库（Moorhead Reservoir）区域发现的考古遗存并不算醒目，但已记录的18处遗址足以证明该区域曾被原住民大规模开发利用，这表明有必要开展探索性发掘工作。其中编号为24PR8与48CA6的两处遗址，其居住与活动强度明显高于其余遗址，应作为优先研究对象。据估算，对这两处遗址开展充分调查各需0.1个发掘单元。此前针对大平原西部带有考古遗存的水库开展的工作经验表明，高强度发掘几乎
