You are looking for a small (50ml) camoed screw top container that holds a log only.
You cannot see it from the ground.
Please be careful if trunk is wet. Moss is quite slippery (decent upper body strength would be a bonus )
PLEASE DO NOT ATTEMPT THIS CACHE IF YOU ARE NOT PREPARED TO REPLACE IT AS PER ORIGINAL - I suggest taking a pen on the climb to sign the log while elevated.
Decending may prove trickier than the climb.
Congratulations to lalest on FTF
