Geologic mapping of this and other 7½-minute quadrangles in New Mexico is being cooperatively funded by the USGS through the STATEMAP program and with matching funds from the Bureau.

These maps are open-filed as they become available. Initially, maps are posted as PDF files of scans of the hand-drawn linework, and later as full color maps and GIS products. These files can be downloaded for free or may be purchased on CD-ROM.
These maps are subject to frequent revisions and may be unavailable when being revised. Map Reference dates show the time of initial compilation; Map Revision dates, when given, indicate the most current version of the map; Last Modified dates for files may not accurately reflect the time the map was last revised.
