A volcano monitoring “spider” was deployed by helicopter to the Oso landslide to track ground movement and seismicity while search-and-rescue operations were ongoing. The spider was equipped with a seismometer (mounted on the far left leg) to track ground shaking and GPS (a dome-shaped instrument on the upper mast) to track subtle ground movement.

Upriver view of the Colorado River where it meets the ocean. This photo was taken after the Minute 319 pulse flow to to simulate natural spring floods. Water provided by the Minute 319 agreement between the United States and Mexico is intended to promote riparian habitat restoration along the river in its delta.
