The Land of the cave dwellers, and their leader Professor's home is a location with many small under-tree caves & burrows. During the day the area resembles a Rainforest with the nearby river and marsh. This is a multi-cache where you will need to find the clue at the first stage to help you with the missing coordinates for the Cave Dweller cache container location: N 44.014580 - W _ _ _._ _ _ _ _ _
The hint may help you. :)
( i recommend good sturdy hiking water-resistant footwear for this cache as its located in an area with possible muddy spots after a rain fall. )
