Second cluster. — The springs of this group are out on a flat place ex- 

 tending over most of the space between the river and the butte at the 

 foot of which the first cluster is situated. Four temperatures taken here 

 in 1871 are, 122° F., 145° F., 162° F., and 165° F. These, however, are 

 but a few of the springs at this place, as the map shows. 



Third cluster. — This includes the springs at the north base of East 

 Fork Butte. Two of the springs are well up on the slopes. The follow- 

 ing are temperatures taken in springs at the base : 126° F., 126° F., and 

 930 p. This cluster would be included with the fourth cluster, but the 

 drainage of the latter is towards the main open basin. 



Fourth cluster. — This comprises three or four springs between the 

 buttes. They have temperatures of 157° F., 167° F., and 167° F. All 

 the springs of the group are only of slight im[)ortance. I have referred 

 to them simply to make the description of the basin as complete as 

 possible. 



CAMP GROUP. 



The trail that follows down the East Fork of the Fire Hole River 

 leaves the latter stream at the "Butte Group" and passes between the 

 two buttes out into the broad open portion of the valley, which is here 

 a wide, marshy tract covered with a rank growth of grass in most 

 places. Turning southward along the west side of the marsh we soon 

 reach the favorite camping place in the basin, on a small stream of good 

 water at the edge of the timber, nearly two miles east oi the Fire Hole 

 Eiver and a mile and a half from the East Fork. Back of this camping 

 place, at the foot of the buttes, surrounded by timber which conceals 

 them from view from the other portion of the basin, is a number of springs 

 to which I have given the name of "Camp Group." They have never 

 before been mapped, and are of considerable beauty and various in form, 

 although there are no geysers among them. They are somewhat above 

 the general level of the basin, on a flat place which narrows above into 

 a ravine, and again spreads out into a marshy space that was once a 

 spring area, as the grass-covered mounds now in it show. The follow- 

 ing are the springs of the group :
