The Parker Lake closure is the Cusick Survival School area. It starts at the power lines on Tacoma Creek road and follows the road up around Timber Mtn and down Ruby Creek road, back to the power lines and returning to Tacoma Creek. It is a hunting closure for everything, all year round, except for 2 Moose tags ML, 2 Moose tags Archery, and 5 deer tags for archery and ML each on a special draw hunt.
Hope that helps. The Parker Lake Closure is listed in the back of the hunting regulations.
