 Beautiful spring, with dark, 



green-tinted water. 

 This cone is probably an old 



geyser. It is lined with 



globular masses. 

 The walls are vertical, and the 



water bulges from an orifice 



of about a foot in diameter. 

 Beaded Geyser, with othjer 



springs back of it. 

 Quiet ; white-lined spring. 

 White-beaded flat basin. This 



is a geyser that spouts aJb 



times. 

 Beautiful pink cone, with a 



second cone close by ; also, a 



small pool near it. 

 Leathery-lined spring. 



Eed springs, in which there is 



a strong odor of sulphurefc- 



ed hydrogen gas. 

 Gray-linod spring ths-t gives 



ofif bubbles of sulphureted 



hydrogen gas. 

 Beautiful bluish-green tinted 



spiing in sulphur-lined basin. 



Lemon-yellow, funnol-.shaped 

 spring, with iron-lined basin 

 below; gives off hydrogen 

 sulphureted gas. 



In hard geyserite ; bulges a lit- 

 tle and gives off hydrogen 

 sulphureted gas. There are 

 other similar springs near 

 this one. 



> Two outlets on hard deposits 



Brown-lined basin in hard gey- 

 serite ; boils vigorously, and. 

 has considerable overflow. 



Fissure in hard geyserite. 



Ratherquiet, brown-lined pool, 

 with a hole at one end juat 

 outside of the pool. 



A red pool, receiving water 

 from 24, which sinks in a 

 shallow pool still further be- 

 low. 



Fissure-like near the edge of 

 the lake north of the Steady 

 Geyser. 



A rather powerful geyser. 



Back of the Steady Geyser, and 

 receives water from the
