GEOLOGICAL SURVEY OF THE TEERITOEIES. 



A hundred yards distant from The Giantess \Yas a siliceous coue, very 



symmetrical but slightly corrugated upon its exterior surface, 3 feet in 



height and 5 feet in diameter at its base, and having an oval orifice 24 



Fig. -5 9. by 36J inches in diameter, 



with scalloped edges. Xot one 

 of our company supposed that 

 it was a ge^'serj and among so 

 many wonders it had almost 

 escaped notice. While we 

 were at breakfast u^dou the 

 morning of our departure a Col- 

 umn of water, entirely filling 

 the crater, shot from it, which, 

 by accurate triangular meas- 

 il urement, we found to be 219 

 feet in height. The stream did 

 not deflect more than four or 

 five degrees from a vertical 

 line, and the eruption lasted 

 eighteen minutes. We named 

 it '' The Beehive." (Fig. 60.) 



The illustration of the Gi- 

 antess in action, for the use of 

 which in this report, I am 

 indebted to the liberality of the 

 editors of Scribner^s Monthly, 

 shows most admirably the suc- 

 cession of impulses by which 

 the column of water is held up, 

 apparently so steadily for so 

 long a time. We did not see this 

 wonderful geyser in operation 

 during our visit; but it has 

 been so graphically described 

 by Mr. Langford, and so faith- 

 fully depicted by Mr. Moran, 

 the artist, that little more need 

 be added. 



The Fan Geyser consists of 

 a group of five geysers, which 

 play at one time, throwing the 

 water in every direction. 

 There is one quite conspicuous 

 cone, marked on the chart. 

 Pyramid, which is now extinct, 

 except that from the summit 

 steam is constautl}^ escaping. 

 This has been a geyser of some 

 importance, and has built up 

 a structure 25 feet high, and 

 100 feet in diameter at the base. 

 Near it is a quiet spring with a 

 most elegantly scalloped rim.
