This
spring break , I got the unbelievable opportunity to explore and camp the
Chihuahuan desert in Big Bend National/State Park. This park is home to so many
perplexing structural features, it's both known as the geologist's paradise and
nightmare. 30 million years ago a series of tectonic events ripped, crushed,
scorched, lifted, buried, and exploded the thick layers of rock beds giving the
desert a tremendous and complex landscape. Although I took a ton of
pictures in the park for my own geo-dork purposes, here are some of the
particularly well composed shots (of complete incidence, I assure you).
Our three grad students and professor Dr.

The desert is
usually more lush and green, but
the past year only
saw 3 inches out of an average
annual
rainfall of 20 inches.

This stuff is tuff. |

Here's the whole gang checking out a stream bed that once supported the small mining community. |
Because of the drought, we only saw one of
these
flowering cacti
about every mile.

The left side is Mexico! This is a canyon
that the Rio Grande
formed between the
Boufacillos mountain range and the
Sierra Rica range
in Mexico.
