Part of the Geologic Atlas of Texas, the Van Horn-El Paso Sheet is an oversize color map that depicts the surface geology of El Paso County and parts of Hudspeth. Jeff Davis, and Culberson Counties, Texas.
Published in honor of E. Russell Lloyd, distinguished Texas independent petroleum geologist, who prior to his death in 1955 edited much of the geological writing concerning the Permian Basin. His geologic interpretation of the Capitan Limestone as a reef, aided in the interpretation of the associated formations and their oil-bearing possibilities. The Capitan Limestone is partly within the area depicted in Van Horn-El Paso Sheet.
