 both of which are increasing. The 

 U. S. Bureau of Fisheries and the U. S. 

 Forest Service have cooperated with 

 the State Game Department in restock- 

 ing many of the streams with trout J 

 rainbow trout, eastern brook trout and 

 mackinaw trout have been introduced 

 successfully.

MOLLUSCS OF THE GREAT BASIN 



This area is of great interest on ac- 

 count of its desert conditions and the 

 Quaternary history of its great lakes, 

 Lahontan, of which Great Salt Lake 

 and Sevier Lake are the descendants, 

 and Humboldt, Walker, Pyramid, Car- 

 son, and other small lakes which are 

 relics of the great glacial Lake Bon- 

 ne ville. The molluscan fauna of these 

 relic lakes is in some respects peculiar. 

 See the paper by Call, On the Quaternary 

 and Recent Mollusca of the Great 

 Basin, in Bull. 11, U. S. Geol. Surv. 



NATURAL AREAS 



*Zion National Park. (A2.) The 

 pinyon-juniper type is best developed 



on the low slopes, while the high moun- 

 tain tops, which are reached with some 

 difficulty, are covered with western 

 yellow pine. The valley bottom bears 

 a typical growth of cottonwood and 

 other stream-bank species of that 

 region. The fauna consists chiefly of 

 small desert animals. This National 

 Park can be reached from Cedar City 

 very easily by auto stage. The eleva- 

 tion is about 5000 ft. in the bottom of 

 the canyon. F. S. Baker. 



*The 'Dinosaur National Monument. 

 (A3.) This reservation consists almost 

 entirely of exposed beds of sedimentary 

 rocks bearing in the crevices, scattered 

 grasses and herbs, and a few stunted 

 juniper trees characteristic of semi- 

 arid woodlands. A typical fauna of 

 small animals is present. Elevation 

 is about 6000 ft. Reached from Ver- 

 nal, Utah (which is 13 mi. distance). 

 The village of Jensen is not far 

 from the Dinosaur quarries. F. S. 

 Baker. 



* Natural Bridges National Monument. 

 (A3.) This area consists chiefly of 

 eroded sandstone rocks with little 

 vegetation. Some juniper, stunted 

 western yellow pine and Fraxinus 

 anomala is present, together with 

 desert herbs. There is a typical desert 

 fauna of small animals. This area is 

 most readily reached from Blanding, 

 Utah, a distance of about 40 mi. over 

 rough mountainous country necessitat- 

 ing horse back travel. The country 

 is almost waterless, and services of a 

 guide are necessary in visiting this 

 reservation. F. S. Baker. 



Rainbow Bridge National Monument. 



Timpanogas Cave National Monument. 



*Bryce Canyon National Monument. 

 (B2.) Mountain Coniferous Forest t in 

 the Sevier National Forest. About 4 sq. 

 mi. of talus slopes, mountains and 

 canyons in Bryce Canyon. Semi-desert 

 conditions showing succession from sage- 

 brush to western yellow pine forest. 

 Reserved on account of scenic aspects, 

 dissected eroded topography known 

 as "Temple of the Gods.' 1 6000 to 

 8000 ft.
