ST HELENS, Wash. — When Mount St. Helens erupted in 1980, hundreds of square miles surrounding the volcano were flattened. Scientists describe the destruction as “moonscaped,” and at the time, it was thought that no life was left. Now, 45 years later, scientists continue to monitor how the environment has rebounded.   One of the biggest changes to the landscape that still exists today is the creation of hummocks, which are deposits from the volcanic deposits that make up hills.
