Grand Teton Np Report
Abstract
An investigation of the insect faunas of Pilgrim and Pacific Creeks was carried out for comparison and contrast of the two streams. The possibility of placer mining at Pacific Creek emphasized the need of the study at this point in time. Systematic collection of insects and physical data from the streams provide information on habitats which are essentially unaltered by man. It is hoped that this research will form the groundwork for future studies and provide data for reference in the event of ecological disturbance of either habitat.
