Tunnel's Critical Ice-Supporting Rock

A single unstable rock embedded in the tunnel wall, propping up a massive overhanging block of ice. Initially, Ian spots it and warns the group (Altos, Sabetha, Susan, and Barbara) to avoid disturbing it, as any nudge would trigger a crushing cascade. Later, Ian deliberately dislodges this same rock to collapse the ice wall, creating a barrier that blocks pursuing ice guards and buys the group time to escape. The rock's removal causes a chaotic avalanche of ice and debris, scattering shards across the chasm edge and forming a temporary obstacle.
