274 REPORT UNITED STATES GEOLOGICAL SURVEY. 



WESTERN GROUP. 



The groups hitherto described are on the east side of the creek. 

 Those ou the west side are equally important as springs, although the 

 geysers are all small, none equaling the Union Geyser, nor even the 

 the Minute Man and Little Giant. Professor Bradley was of the opin- 

 ion that the geysers on the west side were all young. However that 

 may be, none of the mounds are of much height or extent compared 

 with those on the east side. Opposite our camp is the mouth of a creek, 

 named Quick Eun by the party in 1872, but on the accompanying map 

 is called Fall Creek. Springs extend some distance up the valley of 

 this small stream, and remains are found on the sides of the hills; This 

 was called the Western Geyser Division on the map of 1872, and I have 

 retained the name western for the group, although there is probably no 

 true geyser. It is the most western of all the groups in the Shoshone 

 Basin, and contains some large boiling springs. The basin in which 

 the springs occur is on the north side of the creek, mainly on small 

 branches, there being very few on the main stream, which, above the 

 point where Fall Creek joins it, is a cold stream with good drinking 

 water.
