An evaluation of probable bedrock exposure in the Sinus Meridiani region of the Martian highlandsEstimates of the amount of probable bedrock exposures visible in the highest-resolution Viking imaging data for a selected region of the Martian surface are presented. The study region includes portions of the classical low-albedo regions of Sinus Meridiani and Sinus Sabaeus and the high-albedo region of Arabia, and is completely within the cratered highlands of Mars. More than 400 images were used to estimate the percentage of the area of each frame having locally steep slopes. It is seen that 42 percent of the high-resolution frames have less than one percent probable bedrock exposure while three percent of the frames have 15 percent probable bedrock exposure.
