Harquahala Peak Observatory
Overview
Harquahala Peak Observatory was built in 1920 by the Smithsonian Astrophysical Observatory to measure and record solar activity. Although deserted now, from 1920-1925 a hardy group of scientists lived and worked atop the highest mountain in southwestern Arizona (5681 foot elevation). At the time, it was about an hour's drive from Wenden, Arizona, to the mountain, with a 3-hour hike to the top of the peak. Burros were used to pack building supplies, living supplies and equipment to the mountaintop. Most difficult of all to transport were the delicate recording machines and laboratory equipment. Even water had to be transported by burro until collection tanks could be built.
