COMMENTS TO MAP USERS
A geologic map displays information on the distribution, nature, orientation, and age relationships
of rock and deposits and the occurrence of structural features. Geologic and fault contacts are
irregular surfaces that form boundaries between different types or ages of units. Data depicted
on this geologic quadrangle map may be based on any of the following: reconnaissance field
geologic mapping, compilation of published and unpublished work, and photogeologic interpretation.
Locations of contacts are not surveyed, but are plo ed by interpretation of the position of a given
contact onto a topographic base map; therefore, the accuracy of contact locations depends on the
scale of mapping and the interpretation of the geologist(s). Any enlargement of this map could cause
misunderstanding in the detail of mapping and may result in erroneous interpretations. Site-specific
conditions should be verified by detailed surface mapping or subsurface exploration. Topographic
and cultural changes associated with recent development may not be shown.

Mapping of this quadrangle was funded by a matching-funds grant from the STATEMAP program
of the National Cooperative Geologic Mapping Act, administered by the U. S. Geological Survey,
and by the New Mexico Bureau of Geology and Mineral Resources, (L. Greer Price,
Director and State Geologist, Dr. J. Michael Timmons, Geologic Mapping Program Manager ).

Cross sections are constructed based upon the interpretations of the author made from geologic
mapping, and available geophysical, and subsurface (drillhole) data. Cross-sections should be used as
an aid to understanding the general geologic framework of the map area, and not be the sole source
of information for use in locating or designing wells, buildings, roads, or other man-made structures.
Funding for the mapping of Chimney Lake, Lewis Peak, Pinon Ranch and Cornucopia Canyon quadrangles was provided by
the StateMap Program, which is jointly supported by the U.S. Geological Survey and the New Mexico Bureau of Geology and
Mineral Resources. I thank Dr. J. Michael Timmons for logistical support and Stacy Timmons for contact information for local
land owners. Land owners who graciously granted permission for this project include: Benton (for McCasland Ranch),
Coupland, Melton, Hibbard, Mr. Rand French (Marbob Oil, Artesia, NM), Kinkaid (for Cauhape Ranch), Datola, Evrage,
This and other STATEMAP quadrangles are available
for free download in both PDF and ArcGIS formats at:
