The North Clark Historical Museum, 21416 N.E. 399th St. in the renovated 1910 United Brethren Church in Amboy, will be open from noon to 4 p.m. May 10 and May 24 with an exhibit about Mount St. Helens. Admission is free. At 2 p.m. May 10, David Newcomb will present “Return to Life” featuring information about changes in the devastated area since the massive eruption of the volcano forty-five years ago. After training with geologists, ecologists, and biologists, David has been a volunteer with the Mount St. Helens Institute for twelve years. Volunteers repair trails, answer hikers’ questions, and provide extra eyes and ears for the Forest Service. There will be a question-and-answer period following the presentation and refreshments will be served in the basement.
