What you describe sounds a lot like Ausable Chasm in upper New York state. Found those little holes quite fascinating.
That’s a beautiful area. I grew up in western NY and went to college in Albany, so am pretty familiar with the Adirondacks and the Hudson river and Mohawk river valleys.
Don’t miss the humidity at all.
Or the two or three feet of snow.
Or the -12 degrees in January.
But I do miss the trees, especially this time of year, or in two weeks or so.
The Berkshires. Boston and the Cape. Lake George.
Lotta good stuff back there. NY will always feel like home to me, even though now I’ve spent more than half my life on the west coast.
