Officials were investigating Sunday what caused a crack in a Colorado ski lift that forced the evacuation of over 170 stranded skiers and snowboarders.
The gondola lift at Winter Park Resort, about 70 miles (113 kilometers) west of Denver, automatically stopped when it detected the crack in a structural piece of the lift just after noon on Saturday, resort spokesperson Jen Miller said. People riding in the gondolas were lowered down by ropes over the course of about five hours, she said.
