Tinaja
Tinaja is a term originating in the American Southwest for surface pockets (depressions) formed in bedrock that occur below waterfalls, are carved out by spring flow or seepage,[1] or are 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]
Examples
- The Tinajas Altas ("high tinajas") in southern Arizona.
- Several in El Pinacate y Gran Desierto de Altar Biosphere Reserve, Sonora, Mexico.
