The Boston Glacier is located in a large cirque below several mountain peaks in the North Cascades National Park in Washington State . The glacier is an estimated 1 mi (1.6 km) long but nearly 3.5 mi (5.6 km) wide, and the largest in North Cascades National Park. As it extends in an arc from the north of Forbidden Peak , the glacier is also flanked by Boston Peak to the southwest and Buckner Mountain on its east side. Between the peak and the Boston Buckner Mountain glacier is below a known as Ripsaw Ridge ridge . Another ridge extends between Boston Mountain and Forbidden Peak and further north, separating the Boston Glacier from the neighboring Quien Sabe and Forbidden Glaciers . The Boston Glacier has been on a general retreat since the end of the Little Ice Age around 1850. There was moderate growth between 1950 and the mid-1970s, but between 1972 and 2006 the glacier retreated another 1,470 ft (448 m).
