Getting to the slopes burns fossil fuels, but skiers and snowboarders can cut down on emissions by sharing rides to two Southern California resorts. Mountain High and Bear Mountain offer online ride boards to hook up with others heading to the slopes.

Free online rideshare programs are digital bulletin boards that allow participants to hook up with other skiers and snowboarders to share driving and expenses to get to resorts. The programs also provide a way for telemark and Nordic skiers to participate.

Here's how it works. You create an account and a profile for yourself that includes the location the ride is originating. The profile also includes data such as ability level, smoking, gender, age category, and marital status. These parameters are used to offer and find rides with compatible people.

You can request or provide rides, or go for either option. You can search for rides by date and origin. Those providing rides list the number of seats available in the vehicle, estimated departure and return times, and how costs will be divided for the trip. Participants can search for rides, but must be logged in under an account to be able to contact other users to arrange rides.

Rides for the Mountain High and Bear Mountain rideshare program can originate from several counties, including San Bernadino, Riverside, Orange, San Diego, Los Angeles, Ventura, and Santa Barbara. Rideshare options offer multiple towns within most counties. Skiers and snowboarders coming from Las Vegas, Nevada, Arizona, and Northern California can also connect with riders via the rideshare program. Those in rideshare heading to Bear Mountain can also ski or ride Snow Summit via the free shuttle than runs the 10-minutes between the resorts.
