Mt. St. Helens, Washington
The Mount St. Helens graticule is at latitude 46 N, longitude 122 W, and is one of the few places a person could geohash into an active volcano. With mostly mountainous, forested terrain, easily accessible hashpoints are few and far between. The only easy points of access are along Interstate 5, which runs along the western edge, and U.S. Highway 12, which runs east to west across the middle of the graticule.
