 View from the southeast with the Sherman (left) and Grant (right) summits of Mount Baker behind Boulder Glacier is located on the southeast slope of Mount Baker, a stratovolcano near the Pacific coast of North America in the Cascade Range of Washington. Boulder Glacier is the sixth largest on Mount Baker with an area of 3.4 km2 (Post et al. 1971). It flows from the summit crater between Grant Peak (10781 feet) and Sherman Peak (10140 feet) to about 5000 feet. It is noteworthy for retreating 450 m between 1987 and 2005 leaving newly exposed rock and soil behind. Mount Baker (elevation 10,778 feet, 3285m) is a stratovolcano of ice-clad andesite in the Cascades of Washington State in the United States about 30 miles (50km) due east of the city of Bellingham, Whatcom County. ...

Between 1850 and 1950, the glacier retreated 2650 m. William Long of the United States Forest Service observed the glacier beginning to advance due to cooler/wetter weather in 1953. This was followed by a 743 m advance by 1979. The 1979 terminus position is where the small stream enters Boulder Creek from the southwest. Observations in 2005 suggest that the lowest several hundred meters of the glacier is stagnant and will likely disappear. In the pictures, this section of the glacier is gray with rock debris and has few crevasses. On the west side of Boulder Creek is a small waterfall revealed by the recent recession of the glacier. The USDA Forest Service, a United States government agency within the United States Department of Agriculture, is under the leadership of the United States Secretary of Agriculture. ...
 Stagnant, rock-debris covered glacier terminus in 2004 Boulder Glacier may be approached via the Boulder Ridge Trail number 605. The trail passes through a climax community of pacific silver fir and related species of disparate ages with many standing snags. In the fall, a large variety of mushroom species emerge. Near 4300 feet elevation, the trail ascends a lateral glacial moraine. At 4600 feet, the route ascends about 20 feet of Class 2 rock and 120 feet of steep subalpine forest to reach the ridge crest. Soon thereafter, the trail disappears. The term climax community is an ecological term for a community of plants and animals which is the result of succession, where a biological system, a community, or a soil has reached a steady state. ...

Boulder Ridge consists of scenic heather-covered benches and a number of lateral moraines left by vanished glaciers. Glacial retreat has left the upper portion of the ridge barren and unstable and rockfall from the terminus of that portion of the glacier is a hazard to the unwary visitor.
Boulder Glacier is one of the more popular climbing routes on Mount Baker. First climbed on August 24 1891, it is most often ascended in combination with the cleaver between Boulder and Park Glacer to the north to bypass densely crevassed sections of the glacier. At about 10,000 feet elevation, the route passes to the southwest of steep rock and ice to reach the summit ridge east of Grant Peak. August 24 is the 236th day of the year in the Gregorian Calendar (237th in leap years), with 129 days remaining. ...
