An enormous quantity of rollingsteam and vapors, which had attracted our attention from the first, March, 1919] Temperatures of Ten Thoiisuiid Smokes 07^ came from this area. On arriving, we found the whole area on bothbanks of the creek steaming. Most of the orifices were minute, butafter a search of several minutes, we found one large enough to receivethe thermocouple, where wc found a temjjerature of 432° C, the highestwe observed an\\vhere in the Valley. The deposits were very hardwhite material, but the throats were invarialjly purjjlish l:)rown, withoccasional small masses of deposit resembling blue or green glass. Othercrevices round about gave temperatures of 392° C. and 3S2° C. Photo-graphs 3744, 3745, 4144, 4145 (See page 276).. Photograph by Paul R. Hagelbarger FUMAROLE 22. This fumarole was about eight feet in diameter. The main column of steam did not condense until twenty feet from the opening. With the thermocouple hung over the windward side of the hole, as in the picture, we obtained a temperature of 343° C. No. 34. T. ° C. Ill, X 14 E. IX, X 34 E.
