The UA Campus Repository is experiencing systematic automated, high-volume traffic (bots). Temporary mitigation measures to address bot traffic have been put in place; however, this has resulted in restrictions on searching WITHIN collections or using sidebar filters WITHIN collections. You can still Browse by Title/Author/Year WITHIN collections. Also, you can still search at the top level of the repository (use the search box at the top of every page) and apply filters from that search level. Export of search results has also been restricted at this time. Please contact us at any time for assistance - email repository@u.library.arizona.edu.

dc.description	This report includes a geologic map (1:50,000 scale), description of rock units, and description of mineral deposits that were prepared as part of a Master of Science thesis project at Arizona State University in Tempe, Arizona. Preparation of this report included research of previous geologic work and geologic mapping. Mapping was done directly on a topographic base map at a scale of 1:24,000 and aerial photos were used as a field mapping aid. Field work was conducted between September 12, 1991 and May 1, 1992. The Sierra Estrella is a northwest-trending mountain range consisting of a single compact ridge that is 38 km in length, and 5 to 7 km wide. The base of the range varies in elevation from 559 m above sea level near the confluence of the Gila and Salt Rivers in the north, to 788 m near the Gila River Indian Reservation boundary in the south. The highest elevations in the Sierra Estrella are an unnamed peak at 1375 m in the north-central part of the range and Montezuma Peak at 1323 m. This study covers approximately 165 km2 of the Sierra Estrella. Approximately one-quarter of the study area lies within the boundaries of the Gila River Indian Reservation, and it was necessary to obtain a permit from the Gila River Indian Community Council to visit this area. The topography is extremely rugged and irregular, making the area accessible only on foot. However several unimproved dirt roads do extend to the base of the range on the east and west sides.	en_US
