The cone-shaped tent rock formations are the products of volcanic eruptions that occurred 6 to 7 million years ago and left pumice, ash, and tuff deposits over 1,000 feet thick. Tremendous explosions from the Jemez volcanic field spewed pyroclasts (rock fragments), while searing hot gases blasted down slopes in an incandescent avalanche called a pyroclastic flow.
Precariously perched on many of the tapering hoodoos are boulder caps that protect the softer pumice and tuff below. Some tents have lost their hard, resistant caprocks, and are disintegrating. While fairly uniform in shape, the tent rock formations vary in height from a few feet up to 90 feet.
Tent rocks is a very surreal landscape that fits well with infrared photography, especially false colour IR processing.
The following handheld images were taken with my IR converted EOSM. As usual I used Magic Lantern to help him get the best exposure, via the Auto ETTR, and my focus bar script, with IR corrected diffraction, to nail the infinity focus.
This first image was colour processed in LR via the LUT-based profile that I mentioned in the last post.
The next five images were processed in B&W.
