The word "desert" does not conjure up visions of a place where aspens grow, but in Tsegi Canyon at Navajo National Monument, groves of them flourish. The narrow and deep canyon provides the cooler temperatures and moisture that aspens require, just as it provided them to the Kayenta Anasazi who lived and grew crops here more than a thousand years ago. This image is somewhat unusual because the trees were located directly beneath the canyon rim from which they were photographed. The camera and 400mm lens were pointed at a steep downward angle to compose the image, which uses the canyon floor as its background. The long focal length, in addition to being required to closely frame the trees in the deep canyon, compresses the perspective of the image. Among other things, this makes the tall trees appear relatively normal even though they are photographed at a very steep top-down angle.
