198 THE MOUNTAIN. 



SPRING VALLEY derives its name from its abundance of 

 springs, which are mostly thermal or saline ; many of them 

 being a saturated solution of common salt, and having a 

 temperature of 10 to 80 Fahr. 



Near the mouth of the river Jordan are the Warm 

 Springs of Lake Utah. The water of the Great Salt Lake, 

 according to Fremont, is a " saturated solution of common 

 salt. " The water is perfectly limpid, and has a specific gravity 

 of 1*110. It contains, besides chloride of sodium, sul- 

 phate of soda, chloride of magnesium, and chloride of cal- 

 cium. 



Northwest of BEER SPRING, and 230 miles from Fort 

 Hall, there are a number of hot springs. They emerge from 

 the rocks with considerable force, and have a temperature of 

 164 Fahr. They contain chloride of sodium, sulphates of 

 soda and lime, magnesia, and oxide of iron. The rocks of 

 the neighborhood seem to be volcanic. They are near lati- 

 tude 42 10' N., and longitude 115 10' W. 



Northwest of Hot Springs, 120 miles, in latitude 44 11' 

 N., and longitude 111 W., are the HOT SPRINGS OP MAL- 

 HEUR RIVER. Their temperature is 193 Fahr. They are 

 1880 feet above the level of the sea, and are strongly charged 

 with common salt. 



West of Malheur River, 200 miles, are the HOT AND 

 WARM SPRINGS OF FALL RIVER. They are in latitude 44 

 40' N., and 121 5' W. Some of these springs are 89 F., 

 others being 134 F. The region here, according to Fre- 

 mont, exhibits " striking features of volcanic character." 



" The HOT SPRINGS OP PYRAMID LAKE," says Fremont, 

 "are the most remarkable of all the western mountain 

 region. The water boils up from some of these springs like 

 immense caldrons, sometimes with smoke or gas escaping. 

 The water is clear, and has a temperature of 208 Fahr. It 

 is strongly impregnated with common salt." According to 

 Dr. Bell, the temperature of some of these springs have 

 scarcely a parallel in the world. They resemble, to a certain 

 extent, the Great Geyser, the Stokkr, and Spouting Springs
