Wish we could see more details of this vine to help narrowing down further. For now I could only speculating maybe a type of wild grape (Vitis)? Copy & paste the included link below for one in the genus, the possum grape (Vitis baileyana). flowers are needed for a confirmed genus. When it blooms and bears fruits and you still don’t know, please resubmit with photos or flowers, fruits, tendrils, closeup of trunk & twigs. Again I’m only speculating. Thank you & best wishes!
