Paperback. Etat : New. Print on Demand. This book is an extension of the Flora of the Palouse Region published in 1901 by the authors. It covers all of Spokane, Whitman, Asotin, Garfield, Columbia and part of Walla Walla Counties, Washington, and the western portions of Kootenai, Latah, and Nez Perces Counties, Idaho. This region embraces the richest wheat lands of the Northwest, the high rolling hills known locally as the Palouse country. The deep black wheat soils are mainly residual, formed by the disintegration of the Columbia basalt which covers the greater part of the region to the depth of 700 meters or more. The extreme southern part of the area includes the northern portion of the Blue Mountains, here an upraised dome of basalt reaching an altitude of two thousand meters. Separated only by the deep canyon of Snake River are the Craig Mountains, Idaho, geologically a part of the Blue Mountain uplift. Near the Washington -Idaho line, but mainly in Idaho, a series of low mountains extends from near Moscow northward. These mountains are all formed of metamorphic rocks, mainly granite and quartzite. The highest are Cedar Mountain, about meters; Mica Peak, meters; and Mount Carlton, meters. Outlying lower peaks of the same series are Kamiack Butte and Steptoe Butte. The drainage of the region is in general westward. The principal rivers are the Snake and the Spokane. The former has hewn an enormous canyon through the basalt, which averages about 500 meters in depth but where it cuts through the Blue Mountains is nearly twice as deep. All of its tributary streams in the area considered, except the Clearwater, are small and ow in shallow canyons. The Spokane river has lled much of its old valley with glacial gravels, so that only its lower two -thirds now ows in a canyon. On the Spokane gravels occur many species of plants not elsewhere found in the region. Lakes are numerous in Northwestern Whitman County, Spokane County and adjacent Idaho. Little is known of their geological formation, but most of them lie in the channels of existing or of geologic streams. The ora of the greater part of the region is Arid Transition, part of it timbered with Yellow pine (Pinus ponderosa), the rest treeless and character ized especially by the abundance of bunchgrass (A gropyron spicatum). The bottom of Snake River canyon is occupied by an extension of Upper Sonoran plants such as sagebrush and other species which commonly grow with it. The highest dome of the Blue Mountains supports various Hudsonian plants such as Subalpine r, while a broad zone of Canadian Zone plants occupies he slopes down to the Yellow pines. Conspicuous Canadian plants are White r, Engelmann spruce, and Mountain ash. The total ora of the region herein described consists of 20 Pteridophytes, 11 Gymnosperms, 270 Monocotyledons and 838 Dicotyledons. Some additions 0 this list may be expected along the western borders of the area where a number of Upper Sonoran plants are likely to occur, and most of the higher mountain peaks require much more exploration.
