The mountain that sighs at night: What hides behind the sounds?

Enchanted Rock in Texas attracts visitors with legends of ghosts and mysterious sounds at night. Geologists explain the sounds as temperature changes causing the granite to contract and expand, and the lights as reflections of moonlight on water or wet minerals.

Enchanted Rock in Texas is a massive granite dome rising about 130 meters high. At night, creaking and crackling sounds resembling sighs are heard from it, and flickers of light may appear on its surface. Ancient legends of the Tonkawa and Comanche tribes linked the phenomena to warrior spirits, a princess who committed suicide, and a leader condemned to wander eternally. Modern visitors report experiences of peace alongside unsettling feelings. However, geologists explain that the sounds result from the contraction and expansion of granite due to temperature changes, and the lights come from the reflection of moonlight on water or wet minerals. The rock formed about 1.1 billion years ago and is a protected nature reserve.
