ALG-382, Big Boulder Arch II, North Idou Maze Area. 13.2 meter span (measured), 8 meter height (estimated). GPS 32R 550517 2751655. This arch is located behind ALG-381 (Windows View Arch). Once again, this arch is a challenge to photograph. The entire arch cannot be captured. This photo, taken late in afternoon, is probably the best that one can take. A big boulder sitting under the arch, and a second arch located just above them, are both not visible in the photo. The dark area seen behind the monolith in the background of the photo (just at the left base of the arch) shelters ALG-377 (Triple Arch).
