Snowking Mountain and Mount Chaval anchor this high-elevation landscape in the North Cascades during the early twenty-first century. The map reveals a dense concentration of alpine hydrology, characterized by a series of high-altitude basins and tarns. Notable water bodies include the tiered Upper Jordan Lake and Lower Jordan Lake, as well as the Granite Lake system featuring Lake Number 1, Lake Number 2, and the larger Upper Granite and Lower Granite basins. The drainage patterns are defined by the headwaters of Illabot Creek, Otter Creek, and Boulder Creek, which carve deep paths through the steep terrain between peaks like Razorback Mountain. This survey provides a precise record of glacial features and mountain water sources, showing the relationship between small isolated lakes such as Whale Lake, Arrowhead Lake, and Found Lake and the larger creeks that they feed.
