Mount Rainier National Park is a National Historic Landmark
Mount Rainier National Park was designated a National Historic Landmark February 18, 1997. The park is located in Pierce and Lewis Counties of Washington state, about 50 miles (100 kilometers) southeast of the Seattle-Tacoma metropolitan area.
Of the 236,381 acres that encompass Mount Rainier National Park, approximately 97 percent is wilderness and 3 percent is the National Historic Landmark District.
Stunningly beautiful Mount Rainier is the most prominent peak of the Cascade mountains - an active volcano that last erupted approximately 150 years ago (the last great eruption was about 2,000 years ago). Mt. Rainier stands almost three miles above the lowlands to the west and 1.5 miles higher than adjacent mountains.
