Geology of the Chama Basin

Spencer G. Lucas, Kate E. Zeigler, Virgil W. Lueth and Donald E. Owen, eds, 2005, 456 pages.

The 56th New Mexico Geological Society Fall Field Conference will be held in the Chama-Ghost Ranch region, previously visited by NMGS in 1960 (Guidebook 11) and in 1974 (Guidebook 25). This conference moves across much of the southern and eastern Chama Basin. It begins outside of the basin in Espanola, then traverses the western Rio Grande rift and southern flank of the Chama Basin to progress to Ghost Ranch at the end of the first day via Abiquiu, Youngsville, Coyote, and Gallina. The second day moves from Ghost Ranch to Chama, and the last day visits Cumbres Pass, Los Brazos, and Heron Lake. There is also a supplemental road log from Tierra Amarilla to El Vado Dam.

Papers from this guidebook are available for download from the NMGS website.
