The Lawn Lake site is a stratified hunting camp situated on a glacial lake outlet river terrace in Rocky Mountain National Park’s upper subalpine forest zone. Its archaeological assemblage represents 9,000 years of hunter-gatherer use as a summer game and plant processing camp for subalpine forest and nearby alpine tundra resource areas. This article’s focus is on the site’s earliest camp levels which contain artifacts and AMS radiocarbon dated hearth charcoal between 8,900 and 7,900 cal yr BP, placing them among the region’s earliest high montane (3,353 m ASL) Paleoindian hunting camps, once part of a network of such sites designed to support systematic high altitude procurement of summer migratory game animals and plant foods in Southern Rocky Mountain subalpine forest and tundra ecosystems. Lawn Lake paleoclimate and paleoecology studies produced long-term pollen records and climate-proxy sediment data for modeling the site’s prehistoric climate and ecology history, useful for interpreting its high-altitude Late Paleoindian hunter-gatherer adaptations.

草坪湖，科罗拉多州（美国）落基山脉的一个高山狩猎营地：洞察早期全新世晚期古印度狩猎采集者的适应和古景观

草坪湖遗址是一个分层的狩猎营地，位于落基山国家公园上部亚高山森林区的冰川湖出口河流阶地。它的考古组合代表了 9,000 年来狩猎采集者作为夏季游戏和植物加工营地的亚高山森林和附近高山苔原资源区。本文的重点是该地点最早的营地层，其中包含文物和 AMS 放射性碳测年的炉膛木炭，年代在 8,900 到 7,900 cal BP 之间，使它们成为该地区最早的高山（3,353 m ASL）古印度狩猎营地，曾经是一个网络的一部分此类站点旨在支持在落基山南部亚高山森林和苔原生态系统中系统地高海拔地区采购夏季洄游动物和植物性食物。
