Late-glacial Pollen Record from the Forest-Steppe Border, Wind River Range, Wyoming

该提案寻求资金支持一项探索工作，以确定露湖的古气候潜力，露湖位于怀俄明州风河山脉的森林草原边界附近。该遗址也正好位于威斯康辛州晚期冰川高峰期的外围。由于这些原因，它是监测末次盛冰期气候和植被变化的理想地点。20世纪60年代初的初步数据表明，湖泊沉积物可以延伸到19000年或更长时间。早期资料的可靠性很难判断，因此需要用现代方法重新取芯和定年。末次盛冰期边缘以外的连续湖泊沉积物序列，以及贯穿这一进冰期的连续湖泊沉积物序列是极其罕见和宝贵的。

This proposal seeks funds to support an exploratory effort to determine the paleoclimatic potential of Dew Lake, a site near the forest-steppe boundary in the Wind River Mountains, Wyoming. The site is also just outside of the late Wisconsinan glacial maximum. For these reasons, it is an ideal site to monitor climatic and vegetational changes through the last glacial maximum. Preliminary data from the early 1960's suggest that the lake sediments extend to 19,000 14C years or more. It is difficult to judge the reliability of the early data, so the lake needs to be re-cored and dated with modern methods. Continuous lacustrine sediment sequences outside the margin of the last glacial maximum and extending through the time of that advance are extremely rare and valuable.
