The Washington House has approved a bill making it a misdemeanor to ski in clearly marked closed hazard areas at ski resorts.
Supporters argued that a criminal trespassing charge and a potential $1,000 fine would help deter behavior that causes avalanches and endanger the lives of ski patrol and search-and-rescue workers.
But opponents say criminalizing recreational behavior is overreaching, and could result in young people unwittingly receiving blots on their permanent records.
Opponents favored a $500 fine and more harshly worded signs.
The bill applies to runs that are in-bounds at ski areas but have been intentionally marked and closed off for safety reasons.
The measure returns to the Senate for approval of amendments.
