It was one the most beautiful mountains in America, Mount St. Helens, in Washington State. But what many didn't know was that this peaceful mountain had an explosive past. For more than a century, it had been quiet. But below ground, pressure had been building, and soon, Kaboom! Mount St. Helens would erupt with terrifying fury. Eleven-year-old Jessie Marlowe knew the mountain well, and like many, she never imagined that this serene wilderness could turn deadly. But on May 10th, 1980, Jessie finds herself in the middle of the deadliest volcanic eruption in U.S. history. Trapped on the mountain, she must escape clouds of poisonous gas, boiling rivers, and landslides of rock, glacial ice, and white-hot debris. The newest book in the I Survived series will take readers into one of the most environmentally devastating events in recent U.S. history.
