Marshall Gulch experimental site is located southeast of Mount Lemon, the largest peak of the mountains (32o25'45"N 110o46'0"W). The drainage area is 1.54 km2. Two V shaped ZOBs (schist (SC) and granite (GC)) lie within the Marshall Gulch catchment. Both ZOBs are north oriented with relatively steep slopes (3.2 - 56.4 degrees) which have north, northeast and northwest facing aspects. Elevation ranges from 2311 m to 2476 m for SC basin (area is 0.03 km2) and from 2379 m to 2516 m for GC basin (area is 0.05 km2).
