Trivia Question: Which side of a tree does Lichen grow on?
Silly Answer: The Outside
Useful Answer: In the southern hemisphere, lichen grows primarily on the south side of the tree, but not completely.
Because direct sunlight does not hit the south side of the tree, the bark does not dry out as quickly.
This creates an environment where lichen can thrive. Usually, lichen grows around the entire tree.
This cache is not like lichen. It can be found inside the tree with lichen on the outside. The south side, that is.
