DENVER—Historic avalanche danger caused havoc in the Colorado mountains March 7, shutting down portions of two highways and prompting a rare warning for drivers to avoid a route leading to some of the state’s busiest ski resorts.

After another round of heavy snow, at least three major snow slides buried vehicles and ruptured a natural gas line. No injuries were reported.
