I was first ex posed to Arizona's nature and history in Florence, where I lived as a youngster. I am also an amateur astronomer; my brother-in-law introduced me to the wonders of the night sky when I was a teenager. My interests in Arizona and astronomy fit together nicely with the events that have led to writing this book. One night, I don't remember the date, while observing the sky out in the desert of the Harquahala Valley west of Phoenix, my observing companion, Mike Toye, casually mentioned that Gary Weisner, a local independent geologist, had told him there was an old observatory on nearby Harquahala Mountain. 1 My first vision was of an abandoned building with a classic white dome that once held a telescope. I didn't think much more of the site until one day in the summer of 1990, while my wife and I were returning from u trip to Laughlin, Nevada, driving through the Harquahala Valley, I thought I saw a glint of something on top of Harquahala Moun tain. I began asking questions. My first inquiry went to Dr. John McGraw at the University of Arizona's Stew ard Observatory in Tucson. By letter McGraw told me, "The Harquahala astronomical site was used by the Smithsonian Astrophysical Observatory many years ago, princi pally as a solar observatory. I'm afraid I know very little about this site, though I have seen pictures of it in books." McGraw referred my inquiry to Dan Brocious, the public information manager at Fred Lawrence Whipple Observatory, the modern site of the Smithsonian Astro physical Observatory, south of Tucson. In turn, Brocious referred me to the book lighthouse ofthe Skies,2 a comprehensive history of the Smithsonian's efforts to meas ure the so-called solar constant; 3 here there were the pictures of the "observatory" on Harquahala Mountain, a building quite different from my first vision. The book, how ever, provided only a few details about this site. I was determined to go there myself. Gary Weisner told me of the few times he had been to the site and suggested that I call the Bureau of Land Management (BLM) for more information. I dreaded making this can because I thought the BLM was a police department that kept people off government land. I was very wrong~ the BLM is doing a good job of managing our "public" land. 1 Today, the adopted spelling is "Harquaha]a" (one word), the convention used here in the Preface. Back in the 1920s, the accepted spelling was "Harqua Hala" (two words), the convention used in all other chapters. 2 Bessie Zaban Jones, Lighthouse of the Skies, The Smithsonian Astrophysical Observatory: Backgrowid and History 1846-195 5, Smith sonian Institution, Washington, D.C., 1965. 3 Discussed in Chapter l, the solar constant is a measure of the amount of heat the sun sends to the earth V Vt HARQUA HALA LETTERS At the BLM's Phoenix District Deer Valley office, Jack Ragsdale put me in touch with Rich Hanson, supervisory outdoor recreation planner of the Lower Gila Resource Area. While Hanson cautioned me that access to the site was via a difficult four-wheel road, he encouraged me to go and faxed a map to me. I was on my way. Early one Saturday in November 1990, Mike Toye and I left Phoenix for the summit of Harquahala Mountain. It took us two hours to drive to the base of the mountain and then over an hour to go ten miles to the mile-high summit. Only in the last mile or so could we see the odd building prominently placed at the summit of this barren, mile high peak, so typical of the many mountains in the Sonoran Desert. Up close, the narrow two-story structure was odder still. It was completely cov ered with corrugated steel, except for a door with bars on the south side. It certainly didn't look like an observatory, instead more like an old barn. Two concrete water tanks, sagging gutters, an empty secondary foundation, the remains of wooden attach ments and the building itself gave Mike and me the impression that wind, rain and snow had taken their toll. A BLM sign at the site identifies this building as a 1920s field station for the Smithsonian Astrophysical Observatory. That day, in November 1990, was a relatively nice Arizona day, yet at the top of the mountain the wind was miserable. I could only imagine how difficult living on this mountain had been for those who operated the field station. I was determined to find out more about this site. Back in Phoenix I made an appointment with Cheryl Blanchard, archaeologist, at the BLM. In the late 1970s the BLM stabilized the building on Harquahala Moun tain and had it placed on the National Register of Historic Places. To support this ef fort they had gathered what records they could find and documented the stabilization work with photographs. Blanchard let me sit down in a conference room and pour through the BLMJiles. In these files I first saw a few period letters and photographs obtained from the Smithsonian Archives. I was beginning to find the level of detail I was looking for about the beginnings of the Harquahala site. My next inquiry went to the Smithsonian Archives in Washington, DC. They didn't reply for a month, but it was well worth the ,vait and the real turning point in what was by then a legitimate research project. Archivist William Deiss sent me addi tional period letters about the Harquahala site, including an unpublished compilation of letters from one observer to his family, and copies of dozens of period photographs. Deiss advised, "There is additional material here, and I think that you should consider coming here to look at it. This material may be too voluminous to photocopy." What kept me going was the fact that few in Arizona seemed to know about the Harquahala observatory. The few that did, had no idea what it had been used for. I felt I had an opportunity to contribute to written history~ my first effort was an essay, writ ten in the fall of 1991 and published in the 1993 spring issue of The Journal of Preface Vil Arizona History. In addition, I presented the essay orally with slides at the 1993 Ari zona History Convention in Bullhead City. In the spring of 1992 I got a call from Jane Pike, an archaeologist at the BLM. Pike was putting together a brochure about the Harquahala site and wanted to look through my records for anything that might help. During our first meeting I casually mentioned that I thought there was more information at the Smithsonian Archives that could lead to a book, but proper evaluation of this material would involve a trip to Washington. To my surprise, Pike mentioned that possibly the BLM would sponsor such a trip. Before I knew it, I signed on with the BLM as a volunteer research assis tant. Early in August 1992 I flew to Washington and the Smithsonian Archives, and spent the better part of a week combing through records related to Harquahala Moun tain and the Smithsonian Astrophysical Observatory's efforts to measure the solar constant.
