DESCEIPTION. 



Nos. 1 to 12 form a subgroup, or cluster, south of the main springs and 

 nearest to the camp. They are separated from them by a fringe of tim- 

 ber. Near No. 12 are a few mud iiots, one of which is 6 feet in diame- 

 ter and filled with a thick mud paste, which the stream throws into 

 rosette-like masses in its escape. jSTone of the springs in the cluster are 

 very active nor are the temperatures high. 



The main springs, 13 to 33, are in the space at the immediate foot of 

 the butte. Between the butte and a spur on the south side of the space 

 is a marshy area, in which springs 19, 20, and 24 are located. 



Nos. 13, 14, and 15 are on the north side of the spur already indicated. 

 Following up the ravine from these we come out into a broad, marshy 

 valley, in which Nos. IG and 17 are situated. No. 16 is a grassy mound 

 raised about 2 feet above the level. It is 30 feet in diameter, and con. 

 tains turbid, greenish water, in which the temperature is only 92° F- 

 No. 17 is in the grass ; below No. 17 and above are other holes not noted 

 in the table, but which are shown on the map. 



Returning now to the main group, we lind that No. 28 attracts the 

 attention first, on account of the amount of steam which escapes from
