Fun With Lidar and Local Lore: Sinkholes!

I decided to have a bit of fun to further research a bit of unsubstantiated lore regard the karst land I will be farming. The previous owner mentioned that local lore told that one of the many sinkholes on the farm opens to a 20′ x 10′ cavernous room.

Here is the raw LiDAR:

Not much is visible. So when I clip it down so the elevation range is smaller, feature become a bit more apparent:

However, creating a hillshade layer applies illuminated shadows to the hillshade relief makes the sinkholes pop!

I have no idea how to go about exploring the sinkholes even if I wanted to, but I had fun finding them digitally!
