West Rim Snow Canyon hike question

Attachment 36742
From Red Mtn trail you hike for a couple hours and come to the sweet overlook on the white west rim of Snow Canyon located in St. George.

I want to hike for three hours due west from this spot. Anyone ever do that?
It would probably take me due north of the NOTCH that Bo and company hiked to?
I'm planning on going very soon. I heard there are more deep, whiterock canyons
west of snow canyon and Padre Canyon (tuacahn) canyon.

I would love any waypoints of interest or just a howdy.

I will post my pictures and trip report next week.
cheers! jerry
