Glacier Peak [USGS reference] [Wikipedia reference], located 90 kilometres [56.0 mi] south-southeast from Kulshan / Mt Baker [USGS reference] [Wikipedia reference], in Washington State is another active volcano in the Cascadia Volcanic Arc [USGS reference] [Wikipedia reference],
Tucked deep inside its namesake 566,000-acre wilderness a scant 70 miles northeast of Seattle, Glacier Peak is the state's hidden volcano. At a modest 10,541 feet, its summit doesn't tower over the landscape like Rainier [USGS reference] [Wikipedia reference], Mt Baker [USGS reference] [Wikipedia reference], or Mount Adams [USGS reference] [Wikipedia reference].
