EEPORT UNITED- STATES GEOLOGICAL SUEVEY. 



vapor tliat could be seen many miles across the desert. Along -with these springs 

 are a number of mud springs, or, as they are called, "mud volcanoes," round basins, 

 from 2 to 3 feet below the surface of the ground, and varying from 6 inches to 6 feet 

 in diameter. These were filled with mud and slime, the contents being thrown up 

 and violently agitated at regular intervals, accompanied by puffs of steam. Several 

 of these springs had built up cones of hardened mud, and all, with one exception, 

 closed at the top. In this one, the aperture was aboxit 2 inches in width, and emitted 

 a very perceptible odor of sulphuretted hydrogen ; it is said occasionally to throw out 

 mud and water in all directions for a distance of 100 yards. Fragments of this ejected 

 material were found by analysis to have the composition of clay.* 



From what we have jnst written it will be seen that we have a num- 

 ber of Hot Spring localities that are of considerable importance and 

 would attract considerable notice were they not dwarfed by comparison 

 with the more extensive thermal development in the Yellowstone Na- 

 tional Park. 



The springs of ]!^evada and California are usually found in connection 

 with volcanic rocks which are of Tertiary age. The following catalogue 

 presents only the localities without giving the number of springs. With 

 more careful exploration of the West this list can probably be greatly 

 enlarged.
