I attached a PPT with seven slides that may be of use in presentations. 

The first two slide relate to how LiDAR availability determined the order in which the slides were mapped.

The last five are cumulative frequency plots linked to maps for four MLRAs - The Ridges and Valleys has two plots;  we decided the first one was possibly too busy to be very useful.   

Showing them (or at least nos. 4-7) in succession is the best approach to compare the data.   The differences between landslides aside, the most astounding difference is in slope at the randomly selected points (i.e. average slope in the MLRA) .   The last one (Cumberland Plateau) is very different from the others; with a median slope (28 degrees) that is almost twice as steep as the steepest of the other three areas.
