Basic Guidelines: In the strictest sense, nature photography should not include "hand of man elements". Please refrain from images with buildings or human made structures like roads, fences, walls. Pets are not permitted. Captive subjects in zoos, arboretums, or aquariums are permitted, but must be declared, and must focus on the subject, not the captivity. Images with obvious human made elements will likely be deleted from the thread, with an explanation to the photographer. Guidelines are based on PSA rules governing Nature photography which also cover the Nature Forum. Keep your image at/under 1000 pixels on the long axis for in-line viewing. Note that this includes photos hosted off-site at Flicker, Photobucket, your own site, etc. Each member please post no more than just one image to this weekly thread per week. Trees in the high desert, particularly bristlecone pines and some cedars, can take on extraordinarily sculptural shapes. This tree has grown and survived right on the edge of the mesa above Canyonlands, sprouting from a crack in the sandstone. I'm not sure which has been harder on it: the severe climate or the innumerable tourists who have undoubtedly caressed its sinuous, twisted trunk.
