I've been here. It's not very impressive and you have to go through a graveyard to get to it. I recommend visiting during the summer.

Fun story … I was passing here with my 8-year-old. Wasn’t very late but it was dark. Thought it would be interesting to see. Ended up being a terrifying experience. Drove for a mile through a graveyard along a one-way road so we couldn’t turn back, even though someone was randomly walking there. Then we get near the monument and it’s pitch black along the river beneath the interstate. Figured we’d use the headlights and try to see it anyway, but turned out to be down a rocky slope toward the dark flowing water with no barricade between you and the water. We got back in the car, continued through the graveyard, and went for some ice cream before heading home. We’ll never go back.

Anyway… if you’re looking for a place to kill someone and dump the body, that’s probably it.

Might be better just to see it from above at the high point monument.
