On Sunday, February 21st, the birthday of the peace sign, created in 1958 to promote nuclear disarmament,  skiing should be great at the Alturas lake ski area. On Saturday, North Cabin and Sheep Thrills were compressed and flattened with two roller passes. All other trails were ginzu groomed for skate and classic. More grooming will take place on Sunday. Please remember that the Alturas trail system is a nuclear free zone, dogs still welcome.
