Photo & Document Archive now accessible online
October 12, 2021

Archiving data and housing geological collections is an important role the Bureau of Geology plays in improving our understanding of the geology of New Mexico. Our Geologic Information Center has made many of our archived photographs and documents available online via a dedicated portal that uses ResourceSpace, an open-source digital asset management system. Additional archival materials are regularly being added to the system, so be sure to check back frequently.

If you have historical documents, photographs or mine maps and would like to contribute to our archives (or allow us to copy), please let us know.

"Cumbres and Toltec Scenic Railroad: A Geologic Road Log" published
September 23, 2021

This geologic road log describes the diverse geology exposed along the Cumbres & Toltec Scenic Railroad between Antonito, Colorado and Chama, New Mexico. The booklet was designed for use on the annual "Geotrain" excursion offered by the Cumbres & Toltec Scenic Railroad each summer since 2011. The geologic journey begins in the San Luis Basin in the Rio Grande rift, traverses the southern San Juan volcanic field, and ends in the Chama Basin. The booklet includes a brief introduction to the regional geology of the area, a discussion of the engineering geology associated with building and maintaining the railroad, and descriptions of outcrops exposed in road cuts along the rail line.
