A Mexican free-tailed bat flies under a light beneath the McNeil / I-35 Overpass in Round Rock, TX. This particular bat is just one of the half-million bats that make up the Round Rock colony. To get this shot, I had to walk beneath the bridge (in guano) with the whole lot of them flying all around me. Taken on July 17, 2013 with a Nikon D7000 and 50mm f1.8 Nikkor lens.

On a winter trip to Big Bend National Park, I found the Rio Grande down by Santa Elena Canyon to be flooded one day and frozen the next. These photos detail what happened as the ice began to crack and melt, exposing the mud beneath. Taken on January 14, 2013 with a Nikon D7000 and 18-55mm f3.6-5.6 Nikkor Lens. Click image to enlarge.
A hiker takes a much-needed rest after a cold, rainy hike along the backside of the Chisos Mountain range (beneath the Window) to Cattail Falls, a rare desert waterfall oasis that is only active after substantial rains. This hike is little known, since it’s not marked on Big Bend National Park’s maps. Taken on January 9, 2013 with a Nikon D7000 and 18-55mm f3.5-5.6 Nikkor lens. Click photo to enlarge.
Gray skies blanket the Chihuahuan Desert in Big Bend National Park, near Castolon Village and Visitor Center. The prominent peak is called Cerro Castellan, which means “castle-warden’s hill.” Stretching 3,293 feet above sea level, TSHA calls it “a high stack of volcanic rocks.” Read more from TSHA here.

A free climber begins her winter ascent of Big Bend National Park’s Burro Mesa Pour-Off, a desert waterfall that is only active after substantial rains. She made it into the cave, but the slick, volcanic rhyolite at the higher levels of the pour-off made it impossible to continue. Photo taken January 14, 2013 with a Nikon D7000 and 18-55mm f3.5-5.6G Nikkor lens. Entered in the 2013 National Geographic Traveler Contest. Click photo to enlarge.
