In summer, 2012, the areas surrounding
Piers Gorge, Quiver Falls, and Pemene Falls were incorporated into a
State Recreation Area cooperatively operated by
Michigan DNR and Wisconsin DNR. As a result, parking and access for each of these areas now requires either a
daily or annual State Park sticker.
Piers Gorge (final 0.5mi., skipping the shuttle and foregoing Sand Portage) is often done as a big-water, carry-up park-and-play. The gorge often stays open well into winter. (Please scout for any ice-shelves which may overhang critical eddies or areas of shoreline where current may be likely to push you! Some years back, a local paddler who pushed the season had a near-death experience being stuffed into an ice-shelf, struggling to abandon boat and paddle, and did manage to free himself before having to attempt to breathe like a fish.)
