Quick p+g.
Count the number of blue blazes (blue marks on the trees) between the trail entrance at O'connor park (entrance next to Lenape Trail Map) and the end of that trail (Ellison Ave). Add that number to 654 to get the last three digits of the coordinates below.
N 40° 47.767 W 074° 16.???
Then, backtrack up till you see a fallen tree on your left. There is a standing tree next to it. Hidden under some rocks. The cache container is a small lock and lock. No need to BYOP.
Congrats to BigA800 and *Triforce* for the joint FTF!
happy caching!
