State park rangers are leading a series of programs, including some that focus on the 1980 eruption of Mount St. Helens, at two adjacent sites just east of Interstate 5 near Castle Rock.
The summer programs are at Seaquest State Park and the Mount St. Helens Visitor Center, 3029 Spirit Lake Highway, about 6 miles east of Castle Rock.
Programs include ranger talks about the history of the area and the 1980 eruption of Mount St. Helens; guided hikes in the nearby wetlands; and Junior Ranger evening activities. The sites are part of the Washington State Parks and Recreation Commission.
• Mount St. Helens-focused presentations:
Meet at the lower viewing area beside the visitor center. These programs last approximately 15 to 20 minutes and introduce visitors to the ecology, history, Native American culture and 1980 eruption sequence of the most active volcano in the Cascade Mountain Range (all ages).
