- View of Bryce Canyon National Park from Rainbow Point. In the foreground are sandstone hoodoos and in the background is the Grand Staircase-Escalante National Monument, which is managed by the Bureau of Land Management. Bryce Canyon is a unique sandstone formation in southern Utah. It is home to a large number of hoodoos, which are oddly shaped pillars of rock that formed due to different erosion rates for the dolomite that caps them and the sandstone that forms their base. Bryce Canyon is also home to large numbers of cedar trees that spread throughout the canyon.
- Mount St. Helens and surrounding area recover from the historic May 1980 eruption. Shades of white and gray indicate still-bare slopes that were swept by volcanic flows; light green areas at the top of the photo show regrowth of vegetation in devastated areas; dark green areas at the bottom were unaffected by the eruption.
