Hikers peer into the 700-m-wide summit crater of Mount Fuji from its E rim. More than 100,000 people ascend its slopes yearly during the 2-month summer climbing season. A white meteorological observatory (upper right) sits at the summit, which is 240 m above the crater floor. A red oxidized scoria layer across the summit crater rim was emplaced about 2,100 years ago.
