The boardwalk at Spruce Flats Bog

Spruce Flats Bog is formed in an area that was once covered by a dense hemlock forest, which was clear-cut in the early 1900s. Without trees, the water accumulation led to the development of the bog, an ecosystem characterized by acidic, nutrient-poor conditions.

One of the unique characteristics of the bog is the windswept trees. Strong winds from the west bend the tree tops east. This phenomenon is often called Krummholz, meaning crooked wood.
