3. Glaciation of the Uinta and Wasatch Mountains ; by 

 Wallace W. Atwood. U. S. Geological Survey, Professional 

 Paper No. 61. Pp. 93, 15 plates, 24 figures. Washington, 1909.-— 

 " Every large canyon that heads near the crest of the range (Uinta) 

 has been glaciated," and evidence of at least two epochs of glacia- 

 tion appears. During the first epoch the lower limits of the ice 

 were 8,000 feet on the north side of the range and 7,000 feet on 

 the south ; for the later epoch the corresponding figures are 

 8,400 and 8,000 feet. The maximum extent of glaciation in an 

 east-west direction was 82 miles, in a north-south direction 42 

 miles and within this area were one hundred and four glaciers over 

 a mile in length, eight of which were over 20 miles long, the 

 longest extending 27^ miles. 



In the Wasatch range there were 50 Pleistocene glaciers exceed- 

 ing a mile in length, extending on the east side of the range to an. 

 altitude as low as 6,000 to 7,000 feet; on the west side 14 glaciers 

 reached an altitude of less than 6,000 feet and 7 of the 50 larger 

 glaciers reached the shores of Bonneville and parts of their 

 moraines are buried by lake deposits. A very interesting feature 

 of the work is the proof of at least two distinct glacial epochs 

 in the Wasatch, corresponding with the periods of humidity in 

 old Lake Bonneville. 



Mr. Atwood's paper is an important contribution to glacial 

 geology and has given a definite quantitative form to the theories 

 and surmises of the 40th Parallel Survey. h. e. g. 



4. Glacial Waters in Central New York ; by H. L. 

 Fairchild. New York State Museum, Bull. 127, 1909. Pp. 61, 

 42 plates. Albany. — Previous papers by Professor Fairchild 

 have dealt in great detail with the Pleistocene history of central 

 New York. The present paper deals with the ice-border drain- 

 age, particularly with reference to its connection with the present 

 water bodies of this district. The tracing of the ice work in this 

 region necessarily involves detailed descriptions of local phe- 

 nomena, which serve as types of similar occurrences elsewhere. 

 The glacial lake succession in New York state is well brought 

 out by a series of maps which trace the water bodies through the 

 following stages : Local glacial lakes, Lake Newberry, Lake Hall, 

 Lake Vanuxem, free drainage, Lake Warren, Lake Dana, Lake 

 Dawson, Lake Iroquois. The maps and illustrations are up to the 

 high standard set by the New York Survey. h. e. a. 



5. Ground Waters of the India Region, California / by 

 Walter C. Mendenhall. IT. S. Geological Survey, Professional 

 Paper 225. Pp. 53, 12 plates, 5 figures. Washington, 1909.— 

 Included in this report on the water resources of part of the 

 desert region of southern California is a geographic and geologic 

 sketch of the Colorado desert, a region made known by the 

 explorations of William P. Blake in 1853, since which time it 

 has been scarcely at all studied by geologists. Mr. Mendenhall 

 shows that the desert lowland, including the Gulf of Mexico, is 

 due to faulting, — part of it since the Tertiary beds were depos-
