The Smuts and Rusts of Utah

Abstract

As will be seen from the localities given, most of the collections have been made in Salt Lake County. Unless otherwise specified, all of the canyons mentioned are those of the Wasatch mountains in Salt Lake county. These mountains are a few miles east of Salt Lake City, and run north and south. A spur running east and west forms the northern boundary of the city. City Creek Canyon, in this spur, is nearly due north of the city; to the eastward comes Dry Canyon, and nearly due northeast of the city, Red Butte or Reservoir Canyon. Directly east is Emigration Canyon, the pass through which the pioneers came in the early days. To the south of Emigration is Parley's Canyon, and a mile to the south is Mill Creek, then Big Cottonwood, and finally, three miles south on the boundary of the county, fifteen miles southeast of Salt Lake City, is the mouth of Little Cottonwood. For the most part, these canyons have a length of about fifteen miles; and their altitude increases from about 5,ooo feet at the mouth to 8,000-II,OOO feet at their head. In general, the altitudes of Salt Lake County vary from 4,2Io feet, the level of Great Salt Lake, to II,563 feet, at the summit of Twin Peaks. Great care has been taken both in the determination of the host
