California's ski resorts face a deadly season, but the state still lacks a clear count of injuries and deaths. In February, several serious incidents hit major resorts, and an avalanche near Lake Tahoe killed nine backcountry skiers. CalMatters reports California does not track slope accidents. It also does not set a trigger for investigations. Reporters contacted more than two dozen resorts and got no data. Records from the U.S. Forest Service can take months. A father who lost his daughter pushed for reporting laws, but governors vetoed them. Experts say better data drives safer choices and smarter science.

MAMMOTH LAKES — California’s Mammoth Mountain ski resort is open a day after it was shut down when an avalanche partially buried three people.
