This is an aerial of Spirit lake below Mount St. Helen's ten years after the eruption. In the far end of the lake, floating logs form a huge raft. Below the lake bottom, Harry Truman along with his vacation lodge are entombed beneath 600 feet of volcanic ash. The floating logs are now starting to sink root end first and becoming petrified upright, at a very rapid rate by the chemical elements of the lake bottom silts and ash. The Lake water once void of oxygen from poisonous gasses bubbling from the bottom, is now springing back to life with aquatic plants and fish.
