Effect of Visitors on Alpine Ecosystems in the High Tetons

Although major emphasis in this study is on the Lake Solitude region, it was necessary to explore relatively inaccessible sites for comparison with this region. Grizzly Bear Lake, upper Leigh Canyon and Avalanche Canyon were visited and the decision was made to study one or possibly two sites in upper Leigh Canyon and one at Grizzly Bear Lake. Holly Lake and Amphitheatre Lake were also visited because both are readily accessible and it is probable that protection problems similar to those at Lake Solitude exist in these regions. One brief trip was made into the Bridger Primitive Area in the Wind River Mountains where somewhat similar vegetation, landscapes and disturbing factors exist. Project Number 90
