Stephen Mather Wilderness

Posted on Jun 4, 2024 in Washington's Wilderness Areas

ABOUT 
Described by the National Park Service as “the heart of over two million acres of some of the wildest lands remaining”, the Stephen Mather Wilderness within North Cascades National Park captures the essence of Wilderness. Protecting 638,173 acres, this Wilderness offers excellent wildlife viewing opportunities with black bears, mountain goats, pika, grouse, and marmots all frequently spotted by visitors.  

HOW IT WAS PROTECTED 
Designated by the Washington Parks Wilderness Act, introduced by Senator Daniel J. Evans (WA-R) in March 1988. With broad support, the act was quickly passed and signed into law later that year, protecting more than 1.7 million acres in Washington’s three national parks as Wilderness.
