1. Digital Elevation Model (DEM) of Sierra Madera impact structure showing central mountains and raised rim (red outline). Diameter of rim is 9.6 km. Crest of the Central Uplift is 140 m above sea level. DEM compiled by Matthews from four 7.5' quadrangles (CEED image, Texas)

2. USGS Aerial photo of the central uplift. Width of photo approximately 13 km. Submitted by John Wiley
