Excerpt from Lichens and Mosses of Montana: A List Based on Material Collected During the Summer of 1901, With AdditionsThe Mission and Swan ranges of mountains, in northwestern Mon tana, lie parallel with each other, extending north and south in general direction. The Mission range is about seventy-five miles long, ending as a range at the Biological Station. The Swan range extends twenty five or thirty miles farther north. Both ranges were made by faulting. The stronger throw was at the southern end of the ranges, where the high peaks, reaching feet, are found. Between the two ranges the Swan river ¿ows toward the north. It enters Swan lake, still between the ranges, far down the side. From Swan lake the river ¿ows still northward for a few miles, then winds around with a big bend and turns westward through a new channel to its inlet into Flathead lake. That portion of the Swan range which extends north of the Mission range borders directly on the valley north of Flathead lake, rising abruptly from the plain, without foothills.The formation Of the ranges gave to the western side Of each an abrupt and steep face, intersected with many ravines and canyons, with more gradual slopes on the eastern sides. The western base of the upper end Of the Mission range is washed by Flathead lake, which for the greater portion of the distance meets the mountains with abruptness. There is little level or tillable land between, and often scarcely room for a wagon road.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
