Nature
Mount Wilbur is a prominent 9,326-foot peak in Glacier National Park’s Lewis Range, rising more than 4,500 feet above Swiftcurrent Lake in the Many Glacier area. Its steep pyramidal shape, north-side cirque holding Iceberg Lake, and ridges tied to the Continental Divide make it a striking landmark. The mountain is formed largely of ancient sedimentary limestone in the Siyeh Formation, with a dark diorite sill, shaped by the Lewis Overthrust beginning about 170 million years ago. Known for difficult class 4 to 5 climbing and poor rock anchors, it was named in 1885 by George Bird Grinnell for Edward R. Wilbur, linking it to early conservation efforts.
