LAS MORAS CREEK (Kinney County). Las Moras Creek rises on the northern foot of Las Moras Mountain, five miles northeast of Brackettville in central Kinney County (at 29°22' N, 100°23' W) and runs southwest for forty miles, through Las Moras Springs at Brackettville, to its mouth on the Rio Grande, five miles northwest of Quemado in far northwestern Maverick County (at 29°00' N, 100°39' W). Around the creek's mouth flat terrain with locally shallow depressions is surfaced by sand, gravel, and mud that supports water-tolerant hardwoods, conifers, and various grasses. The creek then runs through a steep to gently sloping terrain where scrub brush and various grasses grow. The mouth is surrounded by rolling prairie with oak, juniper, and a variety of grasses.
