...That's what those depressions were at the top of Chimney Rock!

Philip was asking if I knew what I was talking about. It appears that I might. Here are some website links to learn more about them.

Shenandoah National Park's NPS website has a "Did You Know?" feature at the bottom of each page which says this about opferkessels: "Did You Know? The small circular pits (Opferkessels) often found in the rocks of Shenandoah National Park's cliffs and summits are formed by standing water."

Hat tip to James Holland for suggesting that this was the term I was searching for... Thanks James!
