EEPOET UNITED STATES GEOLOGICAL SURVEY. 



In many points this answers the description of spring No. 20. The 

 latter is on a i>latform of deposit on the right bank of the creek, which 

 is here broken into cascades, as is seen in Plate XL. It is also below 

 the main fall in the creek. 



The only other mound or platform likely to be the one Professor Corn- 

 stock mentions is the one with the fissure. My only hesitation arises 

 from the fact that I am unable to locate his camp, as his description 

 would seem to indicate the presence of falls of considerable extent. 

 He says: 



Our little party was camped in a sheltered spot near the brink of a high fall on one 

 of these creeks at the northern end of the range, several hundred feet above the lake, 

 which was not in sight from that point. 



His camp was surrounded with springs, and the only creek at the 

 north end of the range with springs is the Witch Creek. The Fissure 

 Group, also, as I have already said, is about 200 feet above the level of 

 the lake, and it is here that the only falls in its course are located. 

 These reasons, I think, are sufficient to identify the locality as the same 

 one. 



On the left bank of the creek below the springs enumerated in the 

 table there are a number of springs as shown on the map, and on the 

 creek joining Witch Creek, below the group, there is a large collection 

 of springs, which was not visited owing to our limited stay at Heart 

 Lake and the prevalence of bad weather. 



MIDDLE GKOTJP. 



In the map of this group the numbers of only a few of the springs 

 are given. Being obliged to work independently of the topographer 

 the numbers were not placed on the sketches in the field until after the 

 springs were left, and then only those were numbered which were posi- 

 tively identified. The group is located almost entirely on the right 

 side of the creek. A great many of the springs are on marshy ground, 

 and to avoid this the trail to the lake has to keep back of the springs 

 near the foot of the hills. Below No. 1 the water stands on the surface, 

 spreading out on a flat which extends into the timber. None of the 

 springs in this group deserve special mention, and the reader is re- 

 ferred to the table which follows for descriptions of the individual 

 springs. None of the temperatures are high, most of the springs being 

 turbid or mud-holes hid in the grass.
