Photograph of Angleton grass (A. a????latus). King Ranch seed field.

Photograph of Big Bend National Park, showing a part of the Tornillo Flats, where pitting was done last winter in strips. Where the pits are, they caught 2.4 inches of rain and was absorbed into the ground. A thick cover of annuals resulted, mostly 6-week grama, with some seedlings of perennials that were seeded following pitting. The strips not pitted are badly crusted and almost no water penetrated the soil. The area is almost bare. TX-48-176.
