The Chess Draw depression, Otero CO., New Mexico: A hydrothermally-altered, sublaccolithic, alkalic system
— Philip C. Goodell, Virgil W. Lueth, and Tina C. Willsie

The Tertiary alkalic intrusives of the Comudas region of west Texas and southern Otero County, New Mexico, represent reasonable
exploration targets rare earth elements, beryllium, and other metals. Erosionally resistant, unaltered intrusives are prominent on the landscape and
have been extensively studied. This report presents data indicating that other portions of the intrusive complexes are also present in the region, but
they form negative physiographic features. Three drill holes into the Chess Draw Depression, northwest of Wind Mountain, provide the evidence
for the interpretation that Chess Draw is an example of a negative topographic feature caused by extensive hydrothermal alteration.
