Mount St. Helens 1980 Ash Cloud as Seen From Space
Mount St. Helens 1980 Ash Cloud as Seen From SpaceEruptive activity at Mount St. Helens captured the world’s attention on May 18, 1980 when the largest historical landslide on Earth and a powerful explosion reshaped the volcano. A volcanic ash cloud spread across the US in 3 days, and encircled the Earth in 15 days.

1923 Survey of the Grand Canyon of the Colorado River in Arizona
1923 Survey of the Grand Canyon of the Colorado River in ArizonaThe survey of the Grand Canyon of the Colorado River in Arizona. This survey, perhaps the most difficult ever undertaken by government engineers, was made to show the possibilities for development of power. Every feasible dam site was surveyed and the flow of all tributary streams was measured.
