March, 1919] Temperatures of Ten Thousand Smokes 267 



No. 9. T. 274 C. 500 yards southwest of No. 8. 



This steamer was similar to No. 5, with no conspicuous deposits, 

 and was 274 C. at the surface, while the highest we could find three feet 

 down was 240 C. 



No. 10. T. 240 C. XI, S 71 W. Baked Mountain, N 12 E. 



This fumarole was 800 yards straight down the Valley from Camp V. 

 The gully starting at Camp V would lead almost to it. We could tell 

 that it was a hot one, because the steam came out with force, and did 

 not condense until it was a foot or more away from the hole. The 

 temperature at the surface was 240 C. Photograph 3720 (See page 

 266). 



To the west of it was an area of steamers which looked hot but did 

 not register over 100 C. 



No. 11. T. 196 C. Mt. Cerberus, S 60 E. IX, S 81 W. 



This vent was toward Fissure Lake from No. 10, and was about 

 the last one of the line which cuts across the Valley about one-fourth 

 of a mile from the base of Mt. Cerberus. The deposits were brilliant red 

 and orange. The opening was large and the volume of gas great. 

 The temperature at the surface was 196 C., three feet down it was 

 171 C. and six feet down, 191 C. Photographs -4536 (See page 268), 

 4537, 4538. 



No. 12. T. 299 C. Baked Mountain, N 30 E. Mt. Cerberus, 



S 60 E. 86, S 30 W. 



This area lay about 300 yards northwest of No. 11. It was a mass of 

 small fissures with white and brown incrustations. The temperatures 

 recorded were: 171 C., 299 C., 289 C., 250 C., 240 C., 254 C., 

 230 C., 171 C. The cracks are irregular, with but little steam, 

 and it was impossible to force the thermocouple more than six or eight 

 inches below the surface. Photographs 3721, 4539 (See page 269). 



No. 13. T. 181 C. XI, S 55 W. Mt. Cerberus, S 50 E. Baked 



Mountain, N 25 E. 



This was a lone fumarole without much steam, and lay north of 

 No. 12. The temperature, both at the surface and two feet down was 

 the same, 181 C. Photograph 3722. 



No. 14. T. 406 C. XI, S 67 W. Mt. Cerberus, S 52 E. 



This was a long row of small craters, extending about 500 yards in a 

 line between Katmai Pass and Station IX. The fumes from these 

 holes were very acid, similar to those of No. 6 on Baked Mountain. 

 The craters were conical in shape. The fumes came not from the 

 bottoms of them, but from very small cracks in the sides or on the rim. 

 We worked here for several hours and recorded the following tem- 

 peratures from different cracks: 299 C., 323 C., 367 C., 272 C., 

 397 C., 392 C., 406 C., 196 C., 196 C., 323 C., 196 C., 196 C. 

 The deposits were light colored and brown. Photographs 3722 (See 

 page 271), 3723, 3724, 3725, 4540.
