As temperatures drop, grooming has begun again at the Sawtooth ski areas. At Park Creek, Camas, Lupine and Shooting Star were groomed for skate and classic on Wednesday. Skyrocket is scheduled for grooming on Friday. At Alturas Lake, the Trail to the Lake as far as the bridge, Over the Hill, South Loop and most of Sheep Thrills were graded flat before it got too warm to continue on Thursday. Early morning crust cruising may be possible. Snow is predicted for the weekend and setting new classic tracks should work at that point.
