Environnement et pollution: Tent Rocks in Black and White

Publié par ddd à 07:57

Last week Kathy and I returned home from a two-week tour of New Mexico and Texas. Along the way we did several hikes in Big Bend National Park and Enchanted Rock State Park in Texas, as well as Bandelier, White Sands and Tent Rocks national monuments in New Mexico. During the New Mexico leg of our trip we had the opportunity to do a few hikes with our niece and nephew. The following are a few photos from Tent Rocks, captured in black and white (Kathy and I have hiked in this area in the past):

The odd cone-shaped formations that give the area its name are the products of volcanic eruptions that occurred 6 to 7 million years ago which left pumice, ash and volcanic tuff deposits over 1,000 feet thick. Over time, wind and water slowly eroded the tuff, which formed the canyons and tent rocks we see today. Some of these hoodoos, or tent rocks, reach up to 90 feet in height. The only other place in the world where you can find these unusual rock formations is in the Cappadocia region of Turkey.
