Guy Atlee lived and worked in the Kingman area working the Turquoise mine (Mineral Park) and other mines near Chloride (IXL, Wrigley), Cerbat, and Kingman. He is known to have worked and traveled in the Victorville, Topock and other areas of California. Guy’s wife was Rose Atlee and they had a large family. The collection includes images of mines and workings as well as many images depicting daily life in Mohave County. The photos appear to cover a period from about the turn of the century through the 1920s.

Kelsey Boltz has been a registered mining engineer and geologist in Arizona since the mid 1960s. A 1953 graduate of the Colorado School of Mines, he founded Colamer Corporation and Nuclear Dynamics, both companies active in the uranium industry in the Grants Uranium Region of New Mexico in the '50s, '60s and '70s. In 1981 he co-founded Century Capital, Inc., an investment banking and retail brokerage firm which provided several hundred million dollars financing for various industries including natural resource companies. In 1990 he started his exploration consulting company, Boltz Group International, which initiated and managed several mining projects in Mexico, Chile and Bolivia. The collection consists of geologic...

This collection primarily contains economic geologic information on mines in Mohave County, but also includes more general files on other states and mineral commodities. William Crutchfield, Jr. earned his master's degree from The University of California in 1953. He began working for Santa Fe Mining, Inc. in California in the 1960s as a Mining Engineer and later as Exploration Manager. He stayed with the company until the 1980s.

Shorebirds are among the most rapidly declining species in North America (Rosenberg et al. 2019), with many long-distance migrants experiencing the greatest declines (Environment Canada 2020). Nonetheless, not all shorebirds are declining and there may be differences among species and populations using different migratory routes. For instance, previous meta-analyses have suggested that shorebirds using the Mid-Continental Flyway are experiencing more rapid declines than those using the Pacific or Atlantic flyways (Thomas et al. 2006). At the same time, within a species, more northerly breeding populations are experiencing greater phenological mismatches and lower reproductive success than southerly ones (Kwon et...

The Arctic_shorebird_egg_float_tool.xls was developed by Rob Rankin (updated in 2021 by Sarah Saalfeld) to estimate hatch dates, nest initiation dates, nest incubation dates, and nest age based on egg floatation equations developed by Liebezeit, J.R., P.A. Smith, R.B. Lanctot, H. Schekkerman, I. Tulp, S.J. Kendall, D.M. Tracy, R.J. Rodrigues, H. Meltofte, J.A. Robinson, C. Gratto-Trevor, B.J. Mccaffery, J. Morse & S.W. Zack. 2007. Assessing the development of shorebird eggs using the flotation method: species-specific and generalized regression models. Condor 109: 32-47.This tool can be found in the protocol folder.This tool provides species-specific estimates for 10 species: American Golden-Plover (AMGP), Dunlin...

The Climate Adaptation Science Centers (CASCs) partner with natural and cultural resource managers, tribes and indigenous communities, and university researchers to provide science that helps fish, wildlife, ecosystems, and the communities they support adapt to climate change. The CASCs provide managers and stakeholders with information and decision-making tools to respond to the effects of climate change. While each CASC works to address specific research priorities within their respective region, CASCs also collaborate across boundaries to address issues within shared ecosystems, watersheds, and landscapes. These data represent the 9 CASC regions and the national CASC that comprise the CASC network, highlighting...

The collection comprises the Arizona mineral exploration files (mostly for gold and copper) of Cambior Exploration USA Inc. The collection also includes information from acquired companies Westmont Mining and Nicor Mineral Ventures Inc. It contains exploration data as well as submittal information gathered during the 1980s through 1999. Data was not received for some of the company’s major projects during the period, for example Newsboy and Carlota.

Richard (Dick) Hahman was born in Buffalo, New York, in 1936. He grew up in coal mining towns in Pennsylvania, then later in Washington, D.C. He received his master's in geology from the University of West Virginia. His career took him through the U.S., Canada, Mexico, and Chile. He worked for several companies in Tucson, Arizona, before going to work for Conoco Inc. in Oklahoma City in the early 1980s. In the late '80s he started his consulting company, Hahman & Associates, in Las Cruces, New Mexico. He moved back to Tucson around 1997. The collection contains geologic reports, drill logs, maps, assays, photos and field notes from exploration in Arizona and New Mexico.
