Also some vines/bush with thorns. It's growing up like a weed/bush, but also has limbs growing along the ground, quite a bit of these on the hill.

a close up pic of thorns

First is a photo of Lunaria annua, aka honesty or money plant. The white discs are the seed pods from last season. The thorny stems look very much like a rose - there are weedy roses as well as cultivated forms. In my area, I would expect to see roses budded out so perhaps just some sort of bramble :-) And the leaves in the last photo do not belong to the thorny vine - separate plant(s) altogether.

Looks like a lonicera and some ivy in the mix as well.

I think the first is a dessicated Hydrangea blossom thrown out by some gardener or blown in there. It doesn't look like Lunaria to me gardengal. Try picking it up and I bet you will find it is not attached to anything. The rest are Lonicera and Hedera as GG says and not related to the Hydrangea.

I don't know if it looks like one, but money plant would be a possibility. Last year, my mom gave me a bunch of the seeds, and I just randomly tossed them around up on that hill.

As far as the ones with thorns, I thought maybe it was some sort of wild rose. Don't recall them blooming anything last year, but they are a bit out of sight.

Throwing my hat in the ring with the hydrangea crew.

first glance I thought money plant, but blown up it doesn't look right. Could be hydrangea remains.

And I've never seen Lunaria pods skeletonised. Hydrangea does it often.

It's Hydrangea. I've been picking them up all winter. During windy days they blow like tumbleweeds over here from the neighbor's shrubs.
