Do This Now: Ski, hiking, by day and night

10 a.m.-1 p.m. Saturday

Journey 125 years back, when logging was in its prime along the St. Croix River. Winter was the time of the lumberjack. Not only were trees toppled with axes and handsaws, but horses did the work of moving the logs to the river. Come and watch a special guest and his horses logging the old-fashioned way. Meet at the campground. The event will be canceled if the windchill is 15-below. (651-583-2125, ext. 227, mndnr.gov)

Head to the park near Mankato and enjoy two candlelit trails: one for cross-country skiers and another for walkers and snowshoers. Warm up around a blazing bonfire and bring along items to roast (roasting sticks will be provided). Meet at the group campground off Hwy. 68. (507-384-8890, mndnr.gov)
