We are an official Earth Science Information Center for the U.S. Geological Survey, working cooperatively to provide information to the public. We stock all of the USGS 7.5-minute (1:24,000), 1:100,000, and 1:250,000 topographic maps for the state of New Mexico (at our Socorro office). We also carry other selected USGS publications including most of their geologic maps within New Mexico. A complete list of USGS publications available for purchase directly from the USGS is available online. We also maintain a summary of USGS maps available online as free downloads.
