Cave near Blind Hollow, Logan Canyon?

[ndonaldj]

Has anyone heard of a cave near Blind Hollow in Logan Canyon? The story i heard was this guys dad discovered a sink hole cave somewhere in the area. He said the entrance hole was 20 feet in diameter and the entrance rap was aroun 400 feet, followed by another drop of like 300 feet. Im not sure how realistic this is but im still really curious if anyone has heard of a cave in that area that fits the description. He has GPS coordinates for me so i suppose ill see eventually, but still.
Thanks

I have hiked around this area and have not come across any caves.

There are literally hundreds of caves in Logan Canyon so it is entirely possible that there is a cave that fits this description. It would take quite a while to get to the bottom and back out of that one.
