It seems that someone hid a letterbox, NOT associated with geocaching nearby. This cache is in a standing tree, not the downed tree where the letterbox is.
Another installment of our Xtreme Nutz caches.
Welcome to Spring Grove Park.
Multiple readings over three trips got me to within 10 feet once the GPSr settled down. Tree cover will certainly be an issue, good luck! 😀
Enjoy your time here and maybe check out our Jamestown Spring earthcache after you've found this.
