NINE POINT DRAW
NINE POINT DRAW. Nine Point Draw originates in numerous dry washes on the east side of Packsaddle Mountain (at 29°31' N, 103°32' W) about sixty-five miles south of Alpine in south central Brewster County. From its upper reaches, Nine Point Draw runs east for a total of thirty-seven miles, passing between Nine Point Mesa and the Christmas Mountains and skirting the northern slopes of the Rosillos Mountains. It then crosses broad desert flats, enters Big Bend National Park, and cuts the deep defile of Dog Canyon, the dividing point between the Santiago and Dead Horse mountain ranges. About three miles below Dog Canyon it empties finally into Maravillas Creek at a point (29°39' N, 103°06' W) about 4½ miles east of the Persimmon Gap ranger station. Nine Point Draw runs over Quaternary alluvial outwash deposits derived from surrounding Tertiary igneous intrusive formations and over Cretaceous limestones of the Pen and Boquillas formations. Much of the area was once predominantly a grassland, but intense overgrazing virtually destroyed it; in the mid-1980s much of the terrain was dominated by Chihuahuan Desert scrub. In a few protected sections, such as Dog Canyon, Nine Point Draw still harbors remnants of riverbank vegetation, including cottonwoods and desert willows.
