Tinaja

A tinaja [tiˈnaxa] is a surface pocket (depression) formed in bedrock that occurs below waterfalls, that is carved out by spring flow or seepage,[1] or that is caused by sand and gravel scouring in intermittent streams (arroyos).

[2][3] Tinajas are an important source of surface water storage in arid environments.

[2][4] These relatively rare landforms are important ecologically, because they support unique plant communities and provide important services to terrestrial wildlife.

[5] The term originates in Spain, being Spanish for "clay jar", and is used in the American Southwest.
