This satellite image of Washington’s Mount St. Helens comes courtesy of NASA’s Earth Observatory, which notes that tomorrow is the 35th anniversary of the volcano’s eruption and subsequent landslide, which killed 57 people. Scientists still keep a close watch on the site from both the air and ground.

As NASA notes:

On the left side of the top image, log rafts are still visible in Spirit Lake. These drifting rafts are composed of floating trees, thousands of which were uprooted and carried there in 1980. The raft is gradually shrinking in size from year to year as trees sink to the bottom of the lake.

The volcano has been quiet since 2008, which marked the end of a four-year period of activity.
