This is a really cool place. It's stop #15 on the Roaring Fork Motor Nature Trail, near the end, and it's right next to the road. Parking is on the right. I didn't see any figures on the height of the rock wall, but I'm guessing 100-150'. I've seen a photo with the water really gushing, probably right after a rain, but during drier weather it's just a place of 1000 drips - give or take...

I ventured up the hill a little bit for this shot -

and around the bend for this one...
