Nearly an hour from Grand Mound, in the heart of Mount St. Helens’ blast zone, lies the Johnston Ridge Observatory. Erected with the purpose of hosting displays that explore the biological and geological implications of the 1980 eruption, JRO features award-winning films, ranger talks, landscape observations, and lunch for guests. You are even permitted to hike the surrounding areas. During the summers, JRO holds the annual Music on the Mountain series in its outdoor amphitheater. JRO closes for the winter season but opens in May.
