56 General Notes. [ January, 
a band of hostile Indians not robbed it of its entire outfit about 
the middle of the season. 
The second division made a very detailed survey of the Na- 
tional Park, securing the materials for the preparation of a topo- 
graphical and geographical map ona scale of one mile to one 
inch. The geologist not only studied the geology minutely, but 
also sketched every square mile of the area. An unusually in- 
teresting and valuable collection of volcanic rocks and hot-spring 
specimens was obtained. The entire collection of the survey, 
which are of a varied character, will amount to about three tons 
weight. 
The third division explored with equal care the Wind River 
and Teton ranges of mountains, a region of which comparatively 
little was previously known. The peak named by the survey 
Fremont’s Peak was found to be over 14,000 feet in height above 
the sea, with no trace that any human being had ever previously 
reached its summit. Three complete glaciers were discovered on 
the east side of the Wind River Mountains, the first ever known 
to exist east of the Pacific coast. The old glaciated rocks and 
morainal deposits were found on a remarkably grand scale in both 
the Wind River and Teton ranges. 
The object of again surveying the Yellowstone Park was to 
bring it under the system of triangulation which had been em- 
ployed with so much success in Colorado and to make the entire 
work uniform. All the old hot-spring basins were resurveyed in 
great detail, and several new ones were discovered and mapped. 
Soundings and temperatures of several thousand hot springs were 
taken. The history and habits of the geysers were carefully 
studied. The photographer of the survey obtained over fifty 
fine views of the bowls and other curious ornamental details of 
the Hot Springs. 
The results of the season’s labors, though a short one, have 
been on the whole very satisfactory. About 12,000 square miles 
of very difficult country were surveyed, much of it in minute de- 
tail, and a mass of observation secured for the twelfth annual 
report, which will make it of more general interest and value than 
any of the preceding. 
The district assigned to this survey by this department for the 
next Atlas comprises all the area of the Territories of the United 
States north of latitude 41° 45’, east of meridian 117° and west 
of meridian 94°. It is estimated that the mapping of this area 
will occupy five years more, and when this is completed, the sur- 
vey will have mapped over one-fourth the territory of the United 
States west of the one hundredth meridian.
