WINTER SPORTS -- Tracking critters with a naturalist, studying winter ecology and a ladies-only snowshoe trek into an ancient cedar grove are among a dozen outings the public can join in a winter trip series led by the Friends of the Scotchman Peaks Wilderness.

The annual outing series in the proposed wilderness area northeast of Lake Pend Oreille starts Sunday with a snowshoe walk up the Lightning Creek Road to the Regal Creek Trail.

Some of the trips are easy, some are quite challenging.

Pre-registration is required.
