You are searching for an ammo can near a cool double pine.
You are hiking on the Marshal Swamp trail. This trail is well maintained but can be muddy at times. Lots of wonderful swamp land, flora and fauna to look at while you hike. There are always ticks and occasionally mosquitoes so come prepared. The coordinates are very bounce so look for the double pine tree near gz and the ammo can should be lightly tethered there.
