Tectonics of Eastern Flank and Foothills of Front Range, Colorado", [offprint from] The Bulletin of the American Association of Petroleum Geologists, volume 41, number 12. by Boos, C. Maynard & Margaret Fuller - December, 1957

Denver, CO: The American Association of Petroleum Geologists, December, 1957. Duodecimo, stapled. Small arrow in ink pointing to the authors' names. A few of the outer leaves split at the head and tail of the spine, but still firmly bound. Excellent condition. Offprint inscribed by Margaret Boos on the title, "To Sherman Wengerd, with appreciation for his prompt and careful editing of the manuscript, Margaret and Maynard Boos". Geologist Margaret Boos (1892-1978), known as Peggy to her friends, was one of the 20th century's leading experts on the geology of the Rocky Mountains, principally the structure and stratigraphy of the Front Range; carried out important work on minerals and petroleum reserves in the region; and taught at universities across the American West, including establishing and serving as head of the Department of Geology at the University of Denver. She met her husband, C. Maynard Boos, while both were graduate students at the University of Chicago and he became "an ideal field partner", helping her expand on her own work (Jacobson, "Margaret Fuller Boos: Colorado Pegmatite Geologist", Matrix vol. 5, summer 1998. p. 74). Boos became one of the first female members of the American Geological Association and in 1975 the US Board of Geographic Names designed a previously unclimbed mountain in Alaska "Peggy's Peak" in her honour. "Boos was very interested in supporting women students studying geology at Northwestern University; following her death, the Margaret Fuller Boos Scholarship was established as a permanent endowed fund for women graduate students at Northwestern" (Biographical Dictionary of Women in Science). The present paper is on the subject for which Boos and her husband are best know, the geology of the Front Range of the Colorado Rockies, and is listed as a key work in the Biographical Dictionary of Women in Science. The recipient of this inscribed offprint, Sherman Wengerd (1915-1995) was a distinguished petroleum geologist at the University of New Mexico and a leader in his field, responsible for more than 140 academic publications and the supervision of 30 masters theses and PhD dissertations.
