Mountain Sites for Meteorological Observatories. 7 



MT.- RAINIER, MT. SHASTA, AND MT. WHITNEY 

 AS SITES FOR METEOROLOGICAL 

 OBSERVATORIES. 



By Alexander G. McAdie. 



.In 1903 an ascent of Mt. Whitney was made by the 

 writer, and a report upon its availability as a site for 

 meteorological research published in the Sierra Club 

 Bulletin, June, 1904. The elevation 14,515 feet, then de- 

 termined barometrically, was thirteen feet higher than the 

 value determined by precise levels in August, 1905, by the 

 U. S. Geological Survey, Mr. R. A. Farmer, topographer. 



During the present summer ascents of Mt. Rainier and 

 j\.It. Shasta were successfully made. Mercurial barome- 

 ters, a boiling-point thermometer, wet- and dry-bulb ther- 

 momiCters, and other apparatus were carried to each 

 summit. The barometers were the same as those used 

 at Mt. Whitney. Check readings were made at San 

 Francisco and at Portland; and simultaneous readings 

 for sea-level conditions at Seattle, Tacoma, Portland, 

 Spokane, Red Blufif,- and Eureka, through the courtesy 

 of the officials in charge of the Weather Bureau offices 

 in those cities. Professor J. N. Le Conte,"^ of the Uni- 

 versity of California, checked the readings at both peaks ; 

 and Messrs. Franklin, Knapp, Hutchinson, Gardner, 

 Gould, and Elston assisted. 



Camp at an elevation of 5,500 feet was made in Para- 

 dise Valley on the southern slope of Mt. Rainier July 

 i6th-3ist. Leaving camp July 24th, the night was spent 

 at Camp Aluir, and on July 25th the ascent completed. 

 Starting from Sisson, Mt. Shasta was climbed on August 

 4-5. 1905. 



* Professor Le Conte also checked the readings made on summit of Mt. Whitney 

 in 1903.
