*Timpanogas Area. (B3.) Moun- 

 tain Coniferous Forestf in the Wasatch 

 National Forest. 10,000 acres of moun- 

 tains, ravines, canyons, rocks, glaciers, 

 cirques, in Utah County around Mt. 

 Timpanogos. All grazing by domestic 

 livestock has been restricted because 

 of its scenic and ecological interests. 

 Several thousand tourists visit the area 

 each year being attracted by the glacier 

 and mountain scenery. The area pos- 

 sesses great variety of vegetation, very 

 favorable for the study of altitudinal 

 zonation. 5000 to 12,000 ft.

*Big Cottonwood Canyon Watershed. 

 (B3.) Mountain Coniferous Forestt in 

 the Wasatch National Forest. About 

 50 sq. mi. including flood plain, talus 

 slopes, waterfalls, springs, swift streams, 

 mountain canyons, on Big Cottonwood 

 Canyon watershed. Protected by Salt 

 Lake City and the U. S. Forest Service, 

 because the city water supply is derived 

 from the creek and also because of its 

 excellent scenic features. The Forest 

 Service has done considerable experi- 

 mental silvicultural work on this water- 

 shed. In the aspen, fir, and spruce types 

 of forest. Fauna includes beaver, bear, 

 deer, muskrat. 5000 to 12,000 ft.

 conifer-covered areas, regular auto ser- 

 vice up the canyon in summer from Salt 

 Lake City./. M. Aldrich. 



The Shore of Great Salt Lake. (B2.) 

 A good place for study of dipterous 

 fauna, take Saltair trains from the city. 



Get off when the train turns around.

2. NEVADA 

 BY C. F. KORSTIAN 



Nevada is situated in the western 

 United States on the great Intermoun- 

 tain Plateau and ranks sixth among the 

 states in area. 



The greater part of the state is a 

 table land 4000 to 8000 ft. above sea 

 level with lower elevations in the ex- 

 treme southern part, and the tops of 

 the higher mountains reach altitudes 

 in excess of 10,000 ft. The state is 

 bounded on the west by the Sierra 

 Nevada Mountains while the Wasatch 

 Range lies to the east just over the line 

 in Utah. It is crossed by a series of 

 parallel mountain ranges having a 

 general northerly and southerly direc- 

 tion. Between the mountains are broad 

 flat valleys presenting true desert 

 conditions. 



Practically all of the valleys and the 

 plateau country between the mountain 

 ranges were originally a sagebrush 

 desert, the dominant species being 

 sagebrush (Artemisia tridentata) asso- 

 ciated with other small-leafed shrubs. 

 The soil of the sagebrush desert is 

 usually very fertile and yields excellent 

 agricultural crops when watered suffi- 

 ciently; but the supply of water avail- 

 able for irrigation is decidedly limited. 

 Consequently, there is relatively little 

 land under cultivation in the state 

 except in a few of the better watered 

 valleys, such as the Humboldt. Grease-
