GEOLOGICAL SURVEY OF THE TERRITORIES. 



123 



As we go from the river up the hill toward the main springs we meet 

 with a large pool of hot water of about 100 feet diameter. It is 230 

 feet above the level of the river, and ou its edge there are several 

 springs. Of two I took the temperatures, and found them both to be 

 140^ F., the temperature of the air being ()i)° F. and the time of observa- 

 tion 8 a. m. A short distance farther up we came to the main mass of 

 springs, arranged on a series of terraces at different levels. The first 

 terrace is 528 feet above the level of the river. The principal springs 

 are pn the first ten terraces, and as we go up the valley we find that, 

 although there were once many springs here of a most active character, 

 at the present time they have nearly all died out. The first four or five 

 have the hottest springs. The boiling-point at these springs varies from 

 199^.5 to 200°.9. I give the temperatures, &c., below in tabular form. 

 The observations were all made on the 28th of July.
