The seven gully (aka Great Gully Trail) in King Ravine has a maximum pitch of 50 degrees at the headwall. I measured it with an inclinometer. The gully starts at about 35 degrees and gets progressively steeper to the headwall.
Was up there this weekend. Airline to shortline was mostly muddy with very little snow. Once you get to the king ravine trail, snow is more prevalent, but didn't need snowshoe's or anything.
