TravelerThat’s a natural weathering pit (also called a solution pocket or small rock pothole). It forms when: • Water collects in a slight depression in the rock • Sand and small pebbles swirl around in the pooled water • Over time, the abrasion plus chemical weathering slowly deepens and smooths the hole In sandstone areas (like around Cathedral Rock in Sedona), these are very common. When they’re larger, they’re sometimes called tinajas (natural rock basins). Smaller ones look just like this — smooth, oval, and often holding a little water after rain. It’s not a fossil or footprint — just erosion doing its thing over many years 😊
