Blum Basin Falls is a waterfall in Whatcom County, in the U.S. state of Washington. It is located in North Cascades National Park on the headwaters of Blum Creek, a tributary of the Baker River. Fed by two small retreating glaciers and several snowfields on the southern side of Mount Blum, the waterfall is formed by the largest meltwater stream that feeds the mainstem of Blum Creek. The falls tumble 1,680 feet (510 m) down a high glacial headwall several miles within the national park in two distinct stages; the first is a series of slides over rounded rock, above the tree line, and the second is a series of near-vertical plunges to the forested valley below. Although most of the falls is clearly visible, parts of it are obscured by tall pines that grow at its base. There is no trail leading to the waterfall.
