El Encino del Poso (The Oak in the Hole). In this vicinity once stood a magnificent live oak tree that was an early landmark on the South Texas Plains for many years. Noted for its size and its wide canopy, it was located in a large hollow created by livestock that gathered beneath its branches and by winds that eroded the exposed soil. El Encino del Poso was a landmark for early trails and land grants. It also served as the location of a stagecoach station and as the basis for naming Encino (1 mi. N). The tree died in the 1890s, before the formation of Brooks County, the victim of an extended drought. #1414
