Olympic National Park encompasses nearly a million acres, protects a vast wilderness with thousands of years of human history, and several distinctly different ecosystems, including glacier-capped mountains, old-growth temperate rain forests, and over 70 miles of wild coastline. In December, 2016 Congress re-designated the "Olympic Wilderness" as the "Daniel J. Evans Wilderness" to honor Senator Evans' dedication to preserving our wildest places. The Daniel J. Evans Wilderness is one of the wildest places left in the lower forty-eight states.
