Proceed to the posted coordinates at the top of the page. You can cut through the trail next to the listed parking coords and enter the campground.
You are looking for an informational sign which is in front of a very small gated cemetery containing just four grave stones.
Read the sign to fill in the missing numbers N41 32 ABC W082 49.0DE
A = Number of letters in Edward's birth city
BC = Mr. Lockwood's age in years when he died, subtract 18
D = Number of letters in Lydia's maiden name
E = Number of letters in the name of the town where Mrs. Lockwood died, subtract 3
Nice and easy, right? Plug in your answers and go find the container.
Now go find the rest of the caches here (really great multis hidden by HercJerk), go to the beach or play some frisbee golf and enjoy this wonderful state park!
