If you are looking to get out this weekend on Mendota and wondering how to get around the heave that runs from Gov Island to the West to Gov Nelson, I would access ...more at Gov Island. On the West side of the Island there were will a path that goes to a great crossing point for the heave just off the west point of the island (near the duck blind). It is the only spot I've found to cross the heave safely. Good luck and be safe!
