332 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



ception of Washington Territory. The mean elevation of 

 the park above sea-level is between 7000 and 8000 feet, which 

 implies too cold a climate to admit of agriculture, except in 

 certain very limited localities. It is safe to say that not 

 more than one per cent, of this area can, by any possibility, 

 be used for agricultural purposes. Except along the north- 

 ern border, grazing-land exists only in small patches of a few 

 acres each. There are not, so far as is known, any mines or 

 mineral deposits within the park. 



The only occupied buildings within the park are at the 

 White Mountain Hot Springs. A good wagon-road extends 

 from Bozeman, Montana, to this point. From these springs, 

 which form the usual point of departure for excursionists, 

 there are excellent trails to all points of interest within this 

 region to Amethyst Mountain, Yellowstone Falls and Lake, 

 the Mud Geysers, and other objects of interest on the Yel- 

 lowstone River and the Geyser basins. It is unnecessary to 

 specify these trails, as they traverse the country in all direc- 

 tions. In his campaign against the Nez Perces, in 1877, 

 General Howard constructed an excellent wagon -road up 

 the Madison to the Lower Geyser Basin, and thence across 

 to the Yellowstone. His road up the Yellowstone is impassa- 

 ble at present for wagons. 



The third division, under Mr. F. A. Clark, surveyed the 

 Wind River Mountains, a portion of the Wyoming range, 

 and the Gros Ventres range, with a large tract in the Snake 

 River valley. The area lies between lat. 43 and 44 and 

 long. 109 15' and 111, including the upper portion of the 

 Wind River Mountains, with portions of the Wyoming 

 range, the Gros Ventres range, and portions of the Sho- 

 shone Mountains and the Owl Creek range ; also the sources 

 of Green River, Hoback Basin, and the upper waters of Wind 

 River. Mr. St. John acted as geologist, and Mr. N. W. Per- 

 ry as mineralogist to this party. Their reports will prove 

 of general interest. Mines of gold, silver, iron, and vast beds 

 of gypsum, as well as many other minerals, were found. 



The peak named by the survey Fremont's Peak was found 

 to be over 14,000 feet 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
