INTRODUCTION
Permanent lakes occupied several of the large, topographically
closed basins in New Mexico during the last ice age (Fig. 1). Compli-
mentary evidence for changes in climate and hydrology during past
glacial episodes, including evidence for mountain glaciers at higher
elevations, spatial shifts in floral and faunal communities, and changes
in the hydraulic regime of river systems, have shown that ice ages in
the region were characterized by cooler temperatures, increased mois-
ture, and comparatively greener landscapes. The evidence for large
perennial lakes on the floors of today's semiarid basins invokes and
reinforces this picture of a wetter ice-age Southwest.
A comprehensive review of the known distribution of latest Pleis-
tocene lakes in New Mexico was presented by Hawley (1993). Various
morphometric properties and pertinent hydrologic characteristics of the
lake basins are tabulated in the report, and a literature review is pro-
vided. In addition, the regional physiographic and geologic setting is
summarized and aspects of the geology of specific lake basins are pre-
sented.
