This LIDAR image is taken of Mount St. Helens at two different time periods in which the amount of boulders within the crater floor. LIDAR is a great mapping tool for this type of image because it provides a very precise and very accurate image for the two different times and therefore was helpful in predicting if and when Mt. St. Helens would erupt. LIDAR works by sending out lasers to make measurements of the earth and then report back to compile very specific maps that are able to show change if only within a few slight centimeters.
