Mount Blum, or Mount Bald, is a 7680 feet summit of the North Cascades range of the U.S. state of Washington, on the western edge of North Cascades National Park. It is the highest summit of a string of mountain peaks located east of Mount Shuksan and west of the Picket Range. Two small active glaciers rest on its northern flank. Mount Blum was named after John Blum, a United States Forest Service fire patrol pilot who was killed in a 1931 airplane crash.
Six small glacial-fed tarns, called the Blum Lakes, occupy successive bowls on the southeast side of the mountain. Several other ice sheets are spread across cirques and basins on Mount Blum and neighboring peaks. Blum Creek, a stream named for the mountain, drains north and west off Mount Blum and flows into the Baker River, which in turn flows into the Skagit River. The Baker Lake reservoir, one of a series of reservoirs that impound the lower Baker River, touches Mount Blum at its far northeastern segment. Lonesome Creek and Scramble Creek also drain valleys east and north of Mount Blum, respectively. Steep cliffs and drop-offs in the valleys produce some extremely tall waterfalls, such as 1680 feet Blum Basin Falls.
Skiing is an occasional activity on the slopes of Mount Blum. Despite the popularity of the activity, Mount Blum is surrounded nearly on all sides by trail-less wilderness, except for the southern ridge that connects it to Mount Hagan.
Mount Blum is composed of extremely firm granite. This intrusion is common throughout the range, and is much stronger than the looser rock that makes up Mount Shuksan and the Picket Range.
