SALT LAKE CITY (AP) — A group of snowboarders suing one of the last U.S. ski resorts to prohibit snowboarding are arguing in a court filing this week that the ban is not only discriminatory and based on stereotypes, but encourages “hostile and divisive skier-versus-snowboarder attitudes.”

The snowboarders filed the lawsuit in January claiming discrimination on national forest lands that make up most of the Alta ski area in the mountains east of Salt Lake City.
