Yup, bear claw and super chutes are the same thing but super chutes was on some of the old maps in the 60's. I think someone figured out that it's not within SB's lease area and removed it from the map. Those old maps are on the internet so they're worth checking out (I don't have time to paste a link.) So I think that area has been super chutes longer than bear claw but I got the feeling that super chutes also included stuff closer to paradise and maybe even the church. Who knows.
As far as the slide goes, someone should go over there and look at it because, in my experience, those things can be really messy. Often there's a lot of downed trees and maybe root balls. Instead of making a cool new route it might just be a big unskiable mess.
