Mount St. Helens

Mount St. Helens is an interesting mountain because it is by far the most destructive volcano in the history of the United States. On May 18, 1980 a 5.1 earthquake struck and this set off the largest mud slide the States had recorded. The entire north slope of the mountain slid away exposing the huge core of the volcano. This exposed superheated core gave off enormous explosions of ash and rock with huge amounts of steam which melted glaciers causing devastating mudslides which took out whole forests and sweep homes, roads, railways and people along with it.

Golden Gate Bridge – LiDAR Point Cloud

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate strait, the mile-wide, three-mile-long channel between San Francisco Bay and the Pacific Ocean. The structure links the U.S. city of San Francisco, on the northern tip of the San Francisco Peninsula, to Marin County, bridging both U.S. Route 101 and California State Route 1 across the strait. The bridge is one of the most internationally recognized symbols of San Francisco, California, and the United States. It has been declared one of the Wonders of the Modern World by the American Society of Civil Engineers.

The Frommers travel guide considers the Golden Gate Bridge “possibly the most beautiful, certainly the most photographed, bridge in the world”. It opened in 1937 and was, until 1964, the longest suspension bridge main span in the world, at 4,200 feet (1,300 m). (Source: Wikipedia)

Airborne LiDAR was used to capture the bridge and surrounding landscape, that is why the water under the bridge and Suspender wires are not visible.
