Overview

Excerpt from Proceedings of the Academy of Natural Sciences of Philadelphia, 1921, Vol. 73 During the summer of 1920, the writer had a brief, but very successful collecting trip in Glacier National Park, Montana, which disclosed an unexpectedly rich insect fauna. A total of fourteen days, in whole or part, was spent in collecting between July 14 and July 29, inclusive. Glacier National Park lies in northwestern Montana, including within its boundaries a mass of mountain peaks, the highest of which rises to an elevation of feet. It is traversed in a northwest southeastwardly direction by the Continental Divide. On the west side, the waters flow into the Pacific through the Columbia River; on the east side, in the south, to the Missouri River, in. The north beyond the Hudson Bay Divide, to Hudson Bay. Adjoining the park on the east lie the foothills and plains; at the lower altitudes on this side of the park, about 5000 feet, there is a blending of foot hills and mountain vegetation which may in part account for the richness and diversity of the fauna in the dry mountain meadows at this altitude. It was on the east side of the park that most of my collecting was done. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
