I like this elegant vine. What's its name? I saw few pictures of it on the web but all without a name.
Parthenocissus tricuspidata has this climbing habit. Try to see it with leaves to be sure about species (a dried leaf on the first picture seems to fit P.tricuspidata).
Yes, I checked this place again (the previous photos were made in early spring) and it does look like Parthenocissus tricuspidata. Thank you, Tyrlych!
