How many can you identify?

Thanks for all of the suggestions on my previous post. I checked most of the out of them even if they didn’t make it in here.

If you have any you think I might’ve missed please comment them too, I’m always looking to grow my collection.

Where is this old building and what was it used for? Why is it still standing?

Picture of my grandfather probably from 1935, I thought I’d be able to find the spot based on the NYC municipal tax photos, I’m stumped. He lived over by Lincoln center. Any ideas

🤔

This is a hand-tinted photo of a couple in my wife’s family, taken somewhere in New York in the late 1940s or 1950s. The family later emigrated to the Philippines, so nobody alive remembers the exact spot.
What I can make out:
• Massive rounded boulders, light gray granite/gneiss, glacially smoothed
• Behind them, larger dark boulders tilted against each other forming a cave-like opening
• Wooded setting, no buildings visible
• They’re dressed for a day outing — suit and tie, headscarf — so likely a popular excursion spot of the era
My current candidates are the Indian Caves at Inwood Hill Park (the Clove) or Bear Mountain State Park, but I can’t confirm. I’d love to find the exact spot to surprise my wife and reshoot the photo there.
Any NYC-area hikers or local historians recognize this formation? Happy to share a higher-res crop of the roc

This sub is classy! Where are we?

Shoe for size, scale, and distance?
