Park at the nearby parking coordinates (see below), then find the waypoint container at the listed coordinates. A tool might be helpful to get the coordinates of the final, but it shouldn't be necessary. Backtrack just a little after finding the WP, then go for the final.
Waypoint container is a camoed plastic soda bottle preform, five inches long, one inch in diameter. Do NOT attempt to open it! If you think there is something wrong with what you see, think of the cache name to help you get the information you need. DO NOT OPEN THE CONTAINER! Final is a dark cylindrical HCH (Hayward Cheezehead) container, about 4" around and 5" deep. Please use care in removing and replacing the cover
Waypoint is winter-friendly; final is findable in winter, but you might have to search for it.
