Rock Pattern 
Tanque Verde Canyon, Tuscon, AZ 
April 1998

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.
