Cape Mountain

Cape Mountain, or Kiŋigin in Inupiaq, is a prominent peak on Alaska’s Seward Peninsula near Cape Prince of Wales, notable as the northern terminus of the Continental Divide of the Americas and once regarded as the westernmost point of the United States. Rising 2,289 feet above sea level, it dominates the surrounding plateau and drains toward the Bering Sea. Named in 1900 by Alfred Hulse Brooks, it later drew attention for tin discoveries near Tin City, though early mining efforts failed. Its enduring importance lies in its striking geology, including granite, porphyries, cassiterite-bearing quartz, signs of glaciation, and radioactive mineral concentrates.
