A Colossal Problem is an instanced public event in Fallout 76 that takes place inside Monongah Mine in the Savage Divide. The event becomes available after Monongah Mine has been hit by a nuclear strike, causing the public event to appear on the map.
Players enter the mine, prepare during the opening phase, then descend deeper into the mine to fight Earle Williams, a powerful Wendigo Colossus. During the encounter, players must deal with Wendigo spawns, falling debris, fear effects, and other hazards while working together to defeat Earle before the event timer runs out.
