Three hours round trip, if you don't count the half hour to hour we spent enjoying the view up top. Two hours up, included the 500 foot scramble up top. Hold it, I don't remember though if I counted the return down the scramble portion in the one-hour rap back down to the bottom of the gully. Two years ago with a tremendous climber, we were a pretty efficient simul-rapping partnership.
On the climb we did not rope up in the gully, roped the first pitch out of the gully, unroped the next two pitches to the top of the arch, then simul-climbed the remainder. It was a beautiful day.
