Mount Jetté, also named Boundary Peak 177, is a mountain in Alaska and British Columbia, located on the Canada–United States border, and part of the Southern Icefield Ranges of the Saint Elias Mountains.[1] It is named in 1908 for Sir Louis-Amable Jetté, (1836-1920), a member of the 1903 Canadian Boundary Tribunal, leading to the resolution of the Alaska Boundary Dispute, and Lieutenant Governor of the Province of Quebec from 1898 to 1908.[2] The peak of Mount Jetté is not far from the westernmost point in British Columbia.
