THE 'HOTTEST FUMAROLE POUND IN THE VAPEEY 



This little crack had a temperature of 432° C. (8io° F.), more than hot enough to melt 

 zinc. Probably some of the big volcanoes were even hotter, but their centers could not be 

 reached with the instruments available in 1918. 



men as they work ; how they come roar- 

 ing out from the myriad vents ; how their 

 gases are collected for study ; how their 

 temperatures are measured ; how the ex- 

 peditions cook their meals in the puffing 

 steam ; how enormous the volcanoes 

 really are and how tremendously hot. 



The projected expedition of 1919 plans 

 to secure a series of films portraying the 

 remarkable features of the district. The 

 members of The Society will be glad to 

 know that the production of motion pic- 

 tures has been put in charge of Emery 

 C. Kolb, one of the celebrated brothers 

 whose adventurous trip through the 

 Grand Canyon is familiar to all.*

 make itself felt. 



Thus far no mortal man has ever en- 

 tered its portals save only the members of 

 the Katmai expeditions of the National 

 Geographic Society. To all of those 

 who have been thus privileged has come 

 the desire to share the great wonder that 

 has been theirs. They have felt that their 

 mission of making the place known to the 

 world would not be accomplished until it 

 became possible for any one to visit its 

 borders and behold for himself the stu- 

 pendous spectacle there spread before 

 him. 



It is a special gratification, therefore, 

 to the members of the National Geo- 

 graphic Society that the President of the 

 United States has made this region an 

 integral part of the great system of 

 American National Parks, which com- 

 mand the admiration of the world.
