Poljé del Cubillo (Checa): a closed karst valley
The Poljé del Cubillo, in Checa, is a large, elongated closed karst depression with a flat floor and steep limestone borders, formed by limestone dissolution along folds and faults. A seasonal stream runs through it, vanishing down a swallow hole that feeds Cueva del Tornero. Seasonal pools form when groundwater rises.

What a polje is
One of the largest landforms of karst: an elongated, closed valley with a flat floor and steep limestone walls. It forms through rock dissolution, aided by folds or faults that weaken the stone.
A stream that vanishes
Through El Cubillo runs a seasonal stream that suddenly vanishes down a swallow hole (ponor) in the valley floor. Part of that water travels underground to Cueva del Tornero.
Seasonal pools
When the groundwater table is high, small, almost circular seasonal ponds form across the valley floor: the Lagunillas del Cubillo.
