NESTING SANDS

While wild tawny simourvs might nest, the clutches of grays are better suited for hardening on heated sands. A huge cavern in one side of the canyon has been converted for nesting. Ledges dot the sides of the cave, offering places for watchers to perch. A giant dip in the center of the floor, taking up much of the space, has been filled with very fine, soft sand. Heat from deep within the mountains has been directed to heat the rock beneath the dip to a scalding temperature.
