This Depression-era oil painting was created by USGS field man Hal Shelton in 1940. The painting depicts mapping techniques used in the early days of cartography, including an alidade and stadia rod for determining distances and elevations and a plane-table for sketching contour lines. A USGS benchmark is visible near the top.

The USGS collaborated with cooperator U.S. Fish & Wildlife Service to conduct continuous seismic-reflection profiling in the Havasu National Wildlife Refuge. The survey was conducted as part of an applied research and technology transfer effort by the USGS Office of Groundwater Branch of Geophysics in 2007.

Clinker is formed whn rock units that overlie exposed burning coal seams are baked and fused. The red clinker is more resistant to erosion than non-baked adjacent Fort Union Formation sandstone and forms the caps of many plateaus and buttes.
