This mountain in Washington State has an eerie resemblance to the ancient pyramids of Egypt.
Tumtum Mountain is a small volcanic cone located in northern Clark County, Washington, at the edge of a flat region known as Chelatchie Prairie. Its remarkably symmetrical, cone-like shape makes it stand out from the surrounding landscape. The mountain rises to an elevation of 2,004 feet (611 meters), towering approximately 1,400 feet (430 meters above the prairie floor).
Formed by lava flows during the Pleistocene epoch, Tumtum Mountain is part of the Cascade Volcanic Arc. At an estimated age of about 70,000 years, it holds the distinction of being the youngest volcano in Washington’s Cascade Mountains and the westernmost in the range.
