By the early 1900s, logging had removed most of the hemlocks which gave the Black Forest its name. However, in some places you can still find these trees due to property disputes or steep slopes which prevent their removal over a hundred years ago. The Bicentennial Trail takes you to a spot in the forest here where the old growth hemlocks still stand proud.
