Looking upward, this unusual part of Upper Antelope Canyon got its name from the hourglass-shaped feature seen there. A natural optical illusion that plays with visitors' perception of scale and perspective is created when the walls narrow greatly at the middle then spread once more towards the top. Depending on the time of day, the smooth, curved walls here highlight some of the most vivid colour variances in the whole canyon—from deep amber to brilliant orange. Sunlight streaming through the little aperture produces amazing light effects that give the walls internal glow at noon. Particularly remarkable are the acoustics of the chamber; even small sounds create fascinating echoes that accentuate the mystical ambiance of the room.
