Helens in May 1980 carried thousands of trees into Spirit Lake, where a giant log raft formed. Many of these broken stumps, especially those with roots, now float suspended vertically in the water. This phenomenon could have been responsible for erect petrified trees in other volcanic areas such as Yellowstone.The remains of thousands of trees that were violently stripped from the mountainside in 1980 still float on the lake in 2021. But the log mat is more than a reminder of the volcano’s destruction; scientists think it has become an important part of the lake’s ecosystem.The eruption tore thousands of trees from the surrounding hillsides and swept them into Spirit Lake. These thousands of shattered trees formed a floating log raft on the lake surface that covered about 40% of the lake’s surface after the eruption.
