Balcony - 90b
Trip to look at Frank's hole east of Pitchfork towards 75c, left. Dave to start work while George & me visited other end. (We'd looked at QMs on route, amended maps, posted George into holes that weren't drawn for him to come out 20m back out of another unknown hole). We looked at the boulder choke in a loose passage and spied a slot up. On the way back to Dave I said "How about I give you a leg up?" "Sure", said George. He reported a big chamber up there. I didn't believe him coz there was no echo, but checked it. Yep. Back at Frank's hole, Dave had already knocked a lid over it and couldn't do anything, so took no time to convert to our lead. George & I surveyed while he investigated pitch opposite. We borrowed him briefly to rig a traverse in the northern passage. It being late and with a callout of 8 pm, we had to rush on out and join the queue at the entrance pitch. NB I'd walked up from base camp with George and Rob that morning, so quite a long day. Also recalibrated 8W-poney 3 times underground with no success.
