Pulling the rope as tight as it can go, I plant one foot on the side of the shaft and give the rope a tug, then send up a prayer to Zihnal that this is going to work. “Can she do that?” someone snaps. I’m doing it now. Then I lift my other foot and begin to climb up the chimney, using only the right side, walking up stone and leveraging my weight with the rope, hand over hand.
