River Basin Surveys Papers, No. 17: The Excavation and Investigation of Fort Lookout Trading Post II (39LM57) in the Fort Randall Reservoir, South Dakota

The purpose of this paper is to report on the archeology of the multiple components of Site 39LM57 in South Dakota, for which Mr. Mattes has provided the historical background in River Basin Surveys Paper No. 15. Starting in the uppermost level were the remains of Fort Lookout II, probably established in 1831 by the French Fur Trading Co. and subsequently occupied, 1840-51, by the trader La Barge. Below them were traces of two prehistoric aboriginal horizons. The excavations were carried on in accordance with an agreement between the River Basin Surveys of the Smithsonian Institution and the National Park Service whereby sites determined by the Service historians to be of historical significance to the Inter-Agency Salvage Program would be investigated by Smithsonian archeologists.

本研究旨在报道南达科他州39LM57遗址多组成部分的考古学研究情况，马特斯先生已在《流域调查（River Basin Surveys）论文第15号》中提供了该遗址的历史背景资料。该遗址最上层遗存为瞭望堡二号（Fort Lookout II）遗迹，其大概率由法国毛皮贸易公司（French Fur Trading Co.）于1831年兴建，并于1840年至1851年间由商人拉巴热（La Barge）入驻使用。其下方发现两处史前原住民文化层遗迹。本次发掘工作依据史密森尼学会（Smithsonian Institution）流域调查与美国国家公园管理局（National Park Service）达成的协议开展：经该局历史学家认定对跨机构拯救项目（Inter-Agency Salvage Program）具有历史价值的遗址，将由史密森尼学会考古学家开展考古调查工作。
