Boquillas Hot Springs (Texas)

Boquillas Hot Springs is a group of hot (41°C, 106°F) springs about two miles west of Rio Grande Village and five miles north of Boquillas in Big Bend National Park,qv southern Brewster County.

The springs are probably fed by surface-recharged water that circulates to a depth of about 700 meters, where it is heated; it then returns to the surface along faults and emerges from the Boquillas limestone on the bank of the Rio Grande. The rate of flow has been falling since the early twentieth century.
