After grooming sessions on the 13th, 14th and 15th, trails at Alturas Lake were wide, firm and providing a most enjoyable ski experience. The wet snow and subsequent freeze at the beginning of the week left a frozen crusty surface that has been graded and ginzu groomed repeatedly to good results. Skate skiing was excellent on Friday. Classic tracks were laid on most of the Trail to the Lake, Over the Hill and South Loop and hopefully will be added to with grooming on Saturday along with additional corduroy combing of skate lanes.
