"Multiple elevated horizontal to sub-horizontal topographic surfaces are present in the Wichita Mountains, Oklahoma. Elevated topographic surfaces, developed primarily on granite bedrock with gentle slopes of 0.5 to 7⁰,were investigated using 1) Digital Elevation Models (DEMs) extracted from NAD 27 UTM coordinates, 2) Google Earth imagery, and 3) USGS topographic maps. In the western Wichita Mountains prominent topographic surfaces at elevations of 720 ± 5 m, 685 ± 5 m, and 660 ± 5 m are well preserved on at least four different mountains (e.g., Solder's Peak, King Mt.) and can be correlated with similar surfaces on at least seven different mountains (e.g., Mt. Scott, North Mt.) in the eastern Wichita Mountains. A less well developed surface at 585 ±5 m is present in the eastern Wichita Mountains and may not be preserved in the western Wichita Mountains. These surfaces are interpreted to be relict pediments or remnants of a more extensive peneplain subsequently dissected as a result of long term time integrated changes in base level, climate, and/or tectonic uplift. Correlation of elevated sub-horizontal surfaces between the western and eastern Wichita Mountains suggests the Wichita Mountains basement behaved as a coherent crustal block since Mid Cenozoic. The presence of multiple elevated, sub-horizontal, regional topographic surfaces throughout the Wichita Mountains complicates direct correlation of these surfaces to the Southern High Plains peneplain using either a linear regression or an exponential fit along a line of projection. Thus, a finer resolution of the timing for individual elevated surfaces in the Wichita Mountains needs to be established."--Abstract, page iii.
