Libby and I took the dogs up the
trails of the Palisades Canyon Loop (Crazy Cat Canyon) in the Franklin
Mountains today. The trailhead is only a
couple of miles from our house. The
desert is very dry, but the lechuguillas and yuccas and creosote are all clinging
to life amid the harshness. Occasionally,
the light green of a mesquite with newly-sprung leaves brightens the
landscape. The Franklin Mountains are
all about geology, though. The twisted
formations of Lower Ordovician El Paso Group Limestone are mixed with the Upper
Ordovician Montoya Group Dolomite and the Silurian Fusselman Dolomite. There is a spot where the bright yellows and
reds of the fossil-rich (trilobites, cystoids, brachiopods, nautiloids, sponges, etc.) Lower
Ordovician Florida Mts. Formation meets the Silurian light grey-white-to-almost-pink
Fusselman Dolomite in a sharply-defined discontinuity. Amid the jagged limestone and dolomite cliffs and
the stark, spectacular canyons lie the humble beauties of a bright Texas rainbow cactus
or an occasional wildflower.

The desert is so subtle, dry and thirsty, but pretty all the same. Thanks for the pictures!
