Within

The other photo shows this from above - now, this is within. The waterfall (which is to the center opening) is in the other photo(s). As you can see, it was definitely a challenging climb down & back up.

 

(This is NOT at the Old Man's Cave area - for those that are familiar with that location, but it is somewhat relative.)

 

This is at a protected State Nature Preserve and a permit is required to be able to hike there.
