Mount Alverstone or Boundary Peak 180, is a high peak in the Saint Elias Mountains, on the border between Alaska and Yukon. It shares a large massif with the higher Mount Hubbard to the south and the slightly lower Mount Kennedy to the east. The summit of Mount Alverstone marks a sharp turn in the Alaska/Canada border; the border goes south from this point toward the Alaska panhandle and west toward Mount Saint Elias.
Mount Alverstone was first climbed in 1951 by a party led by Walter Wood, during an expedition that also made the first ascent of Mount Hubbard. The successful climbs were tinged by tragedy when, upon returning from the peaks, Wood learned that his wife Foresta and daughter Valerie had died in a plane crash nearby along with their pilot. Mount Foresta, near Mount Alverstone, is named in her honor.
