"Ernst Tinaja is reached by simply walking up the dry wash for about 0.5 mile. The word tinaja (pronounced ti-NA-ha) is Spanish for “large earthen jar” and refers to a basin-shaped water hole, usually carved into bedrock by natural erosion.
These water holes are important sources of water in the canyons and rocky terrain of the Chihuahuan Desert. Insects, birds, snakes, frogs, deer, mountain lions, bears, and other creatures all depend on water sources like Ernst Tinaja for survival. Because of that, be careful never to contaminate any water source with soap, sunscreen, or other pollutants."
