Wild Grapes seen in the last week of June.

This was June end in 2017.
A lot of posts from that visit remain unidentified.

any more pictures of leaves where you can see some complete faces of some leaves?

No. These are the only pictures I have.
When you are on a tour, can hardly spend more time at a place.

i know that’s why they are good for personal memory only. i have at least TEN thousand of such pictures. when i get a moment i try to id them myself for my own file or satisfaction and my parents have/had even more. they used them often to draw and paint collages from the pictures. not every picture going to be identified

yours could be. classified as wild grapes. northern new york state.
good luck. sorry cant come up with a species name. too many cultivars that have escaped

forgot. Vitis spp.

Also, it was seen right next to the water, growing on rocks.

could be

I guess Vitis riparia Michx. looks a close match

how would you prove or disprove that diagnosis
