I found a hold on a rock above me and started to pull myself up off the ledge when Jamie, who’d apparently taken the route I deemed unclimbable, shouted a warning that the rock was loose. I had tested the rock as a hold a couple times and didn’t notice any movement but I trusted her. So rather than pull down on the rock, I jammed my hands into the crack between the boulder and the bedrock to pull myself up and onto the summit!
