Useful information about getting to the area, recreation zones and water hazards are in descriptions of the 2 Mystery caches;
'We'ir this way' and 'We'ir at the boat ramp'
The caches on the eastern side of the river are small metal screw top containers securely wired to a tree.
The containers unscrew so you should not need to undo the tether.
This one was placed sitting in a kayak.
Contains a log only. Bring a pen.
