We conducted a paleoseismic study on the San Andreas fault (SAF) southeast of Cholame, California, to investigate the record of earthquakes along an 80-km paleoseismic data gap between Parkfield and the Carrizo Plain.

A paleoseismic study conducted along the Cholame segment of the San Andreas fault provides evidence for three earthquakes and the amount of lateral offset for the most recent event (1857 Fort Tejon earthquake).

Passive survey for raptors in 2016 were conducted at four sites in the vicinity of the Resolution Copper Project. Survey was conducted at the Whitlow Ranch Dam, two portions of Devils Canyon, and one segment of Mineral Creek, all in Pinal County, Arizona.

The impact of outdoor lighting from the proposed Resolution Copper mine on the night skies as viewed from four observation points is assessed.

An existing model of desert pavement formation suggests desert pavement clasts rise vertically on an accreting eolian mantle and the underlying vesicular horizon coevolves with pavement formation. Results presented here support this model and provide a mechanism whereby eolian material is transported from the ground surface to ped interiors, thereby increasing the thickness of the vesicular horizon help identify the processes of underlying desert pavements.

The Heritage Data Management System (HDMS) is part of a global network of more than 80 Natural Heritage Programs and Conservation Data Centres. HDMS information is available so Arizonans can make prudent decisions weighing future development, economic growth, and environmental integrity.

In developing resource management plans for public lands over which it has management responsibilities, the Bureau of Land Management in Arizona began considering wild and scenic river classifications as early as 1985.
