Underground River Emerges at Dawn in Andalusian Foothills

First rays of nautical dawn strike the limestone cave mouth where a subterranean river spills onto the rocky floor. The water flows over smooth, pale stone into a still pool that mirrors the layered foothills rising in the background. Late summer heat lingers in the clear air after a storm, leaving the rock surfaces damp and darkening the gray limestone. Golden light hits the wet edges of the cave entrance while the distant hills remain in soft blue shadow. Reflections in the foreground pool create a perfect vertical symmetry, doubling the rugged texture of the stone arch and the pale sky above. A thin ribbon of mist rises from the water's surface near the cave threshold.
