Himalayan Glaciers. — Steps have been taken by the Geological 

 Survey of India to survey and mark the positions of the ends of 

 several glaciers; photographs will be taken and observations made at 

 future times, which will determine the changes they undergo.' 



REPORT ON THE GLACIERS OF THE UNITED STATES FOR 1907= 



The snow fall in the Rocky Mountains was so great during the 

 previous winter that the Hallet glacier in Colorado was not uncovered 

 during the summer of 1907, and therefore it is probable that it has 

 made a small advance (Mills). Three small glaciers are reported in 

 the Crazy Mountains of Montana, one each in Big Timber, in Sweet 

 Grass and Rock Creek canyons, respectively (Wolfe and Mansfield). 

 There is no report on the Californian glaciers, but the snow-fall in 

 the Sierra Nevadas was unusually great during the preceding two 

 winters (Le Conte). 



The snow fall seems also to have been excessive in the Cascade 

 Mountains of Oregon, though the annual precipitation at Portland, 

 Oregon, was but normal (Montgomery). The Eliot Glacier, on the 

 northern side of Mt. Hood, continues to retreat. A comparison of a 

 photograph taken in 1907, with earlier ones, shows a marked recession, 

 and the slope at the end of the glacier is much diminished, {Langille). 

 Mr. A. H. Sylvester^ has made a topographic map of Mt. Hood and 

 the region west of it which is to be published by the United States 

 Geological Survey. He observed glacial scratches and old moraines 

 at a considerable distance from the mountain. He reports evidences 

 of a small advance in most of the glaciers which is referable to the 

 heavy precipitation during recent years, but he thinks the Zig Zag 

 and White River glaciers are retreating on , account of the greater 

 activity of the fumarole at their heads, which has melted a large 

 quantity of snow in the old crater of the mountain. In the canyon 

 below White River Glacier he has found ice buried in places by more
