| 説明 | Blackhawk Landsllide, on the Lucerne Valley of California. It broke loose from the north side of the San Bernardino Moutains 17,000 years ago, almost in the geologic now. Some geologists believe it moved as fast as 270 miles per hour and floated on a cushion of air before it plopped down where you see it now. This, they say is the only way it could have achieved the great distance it traveled. (Most landslides just pile up on the bottom of the slope.) In this shot you can see the rectangular hunk of mountain on the left that almost seems quarried out by the slide. You can also see the "gneissic ridge" it hit on the way down, which launched the slide like a ski jump. An older slide lies buried in alluvium on the near side. |
