Tanque Verde Canyon, Tuscon, AZ
The setting: Tanque Verde Canyon is filled with interesting designs on the rocks. This is one example of several obtained on an unusual day - it was cloudy.
Technical detail: TMax 100, 35 mm, Nikon F3HP, Nikon 105 mm lens, f11. It is unusual to use 35 mm, but for this trip the absence of weight was a considerable virtue.
Within Gallery #2: Previous Image.
