126 KEPORT UNITED STATES GEOLOGICAL SURVEY. 



No. 2 is a fissure about 10 feet in length witli a spring about a foot in 

 diameter at one end. This is a sulphur-lined opening in reddish tinted 

 hard geyserite or sinter, in which the water has a temperature of lOTo 

 F. Near No. 2 are a steam vent and a turbid pool of about a foot in 

 diameter. 



No. 3 is a milky-looking pool about 3 by 3 feet, in which the water is 



gently boiling. Sulphur appears to be characteristic of these springs. 



No. 4 is a basin 20 feet diameter, of broken geyserite, in which is a 



second basin in hard deposit with a fissure-like center, which is sulphur 



lined, and gives forth steam. In this the temperature is 1950F. 



No. 5, emerald spring, is somewhat concealed in the timber, and is a 

 handsome, yellowish emerald-tinted pool, measuring 40 by 50 feet. The 

 basin is sulphur lined and has a gray border. The water boils at one 

 end, and has a temperature of 186° F. on the edge of the spring. There 

 is considerable overflow, which goes to the southwest. 



No. 6, Locomotive Spring. — This is a boiling sulphur mud-hole about 

 12 feet in diameter with a raised margin about 3 feet high, composed of 

 mud coated with sulphur. A stake with the name Locomotive was 

 found near the spring, probably i)ut there by some one of the party when 

 building the wagon road. The spring is across the road from No. 1 on 

 somewhat higher ground. Near it is a pool, and the surface is perforated 

 with steam vents and mudholes. 



No. 42 is on the slope of the hill south of No. 5, and is a turbid sulphur 

 spring that spouts. Back of it are several sulphur mud-pots, and the 

 gulch beyond is full of sulphur vents. 



Most of the springs to be described now are in a broad flat depression 

 or basin measuring about 200 by 300 yards. It is from 50 to 100 feet in 

 depth, and besides the springs enumerated contains hundreds of sizzling 

 holes, steam vents, and mud pots. The sketch map accompanying this 

 report will give the best idea of these springs. The hill on the east 

 contains a number of springs, and Nos. 7 and 8 are in a gulch near the 

 wagon road on the south side. Nos. 33 to 37 are at the north edge of 

 the flat which carries the drainage from the group, while Nos. 39, 40, and 

 41 are on the south side. 



No. 7. Blade Geyser is a small spouter at the head of a gulch, where 

 the wagon-road turns to go around the group. It is in dark bluish- 

 black deposit of spouts, with a great deal of steam to the height of 10 

 feet. The water is milky-hued, and has a strong odor of sulphur, which 

 is probably the cause of its turbidity. The water fluctuates. 



No. 8 is a steam vent or fissure 2 by 3 feet, in a rock in the gully 

 below No. 7. 



No. 9 is a whitish pool in a gray basin, about 25 feet diameter. The 

 central orifice measures 2 to 3 feet diameter, and from it there is a con- 

 stant bulging which throws the water in the pool into waves. The tem- 

 perature on the edge is 190° F. 

 No. 10 is a collection of muddy pools, receiving water from No. 9. 

 No. 11 is three mud springs. The ux)per one is a light-colored bulger. 

 The lower ones are lead-colored. 



No. 12 is a greenish- white pool surrounded by steam vents and mud- 

 pots. 

 No. 13. is a collection of greenish mud-holes. 



No. 14 is a turbid milky pool, 25 by 30 feet, which bulges slightly in 

 the center and has a temi^erature of 155° F. 



No. 15 is a constant spouter, throwing a mass of water 5 feet into 

 the air, and occasional spurts 15 to 20 feet. The temperature was not 

 taken. The geyser is at the end of the pool.
