What You’ll See The Siltstone "Cathedrals" You’ll stand at the base of massive, buff-colored spires carved from ancient lakebed deposits. These towering structures give the park its name and provide a dramatic backdrop for photography. Hidden "Caves" & Passages: Unlike the wide-open desert, you'll see the Moon Caves and Canyon Caves—deep, narrow fissures in the rock that create a labyrinth of shadows and golden light. Panoramic Vistas: From Miller Point, you’ll get a bird's-eye view of the entire gorge. What You’ll Do Wander the Slot Canyons: You won't just look at the rocks; you’ll walk through them. The "caves" are actually narrow slot canyons perfect for exploring on foot. Capture Photos: Whether you’re a pro or just using your phone, the textures of the bentonite clay and the unique "pipe organ" formations offer endless angles. Hike the Overlooks: Take a moderate hike up the stairs to reach the best viewpoints in the park, feeling the scale of the Great Basin Desert.
