Goat Rocks was a Volcanic Dome rock formation that existed on the north slope of Mount St. Helens , an active volcano in the state of Washington , United States . Goat Rocks was originally created in a series of eruptions between the years 1800 and 1857 , which is the eruption cycle now referred to as the Goat Rocks Eruptive Period. Beginning in March of 1980 , the north face of the mountain beneath Goat Rocks began to buldge outward due to the intrusion of Magma . Goat Rocks was obliterated in the major eruption event on May 18 1980 that destroyed the entire north face and top 1,300 feet (400 m) of the mountain. SEE ALSO |
