Rhododendron Trail is a good way down. When you are almost to the water, turn right. You’ll see the Five Points Trail (see waypoint). At that point, STOP. Don’t enter water. Look for a long log up from water and an overgrown trail that opens up a bit. You can sort of follow that to the correct area.
My favorite type of geocache, a well stocked ammo can at the end of a nice hike. Stick to the trails to find this cache (trail has been re-routed away from ground zero). The GPS signal bounces at ground zero so rely on your previous caching experiences. Please trade fairly and rehide well.
