Big Sur coast just north of Kirk Creek
A two-day rainstorm from January 26-28, 2021 caused numerous mudslides, debris flows, and other issues along California's coastal Highway 1 through Big Sur. This section is just north of Kirk Creek, at a drainage where mud was washed across the roadway. Plumes of the muddy runoff are clearly visible in the ocean.

California Highway 1 north of Wild Cattle Creek
A two-day rainstorm from January 26-28, 2021 caused numerous mudslides, debris flows, and other issues along California's coastal Highway 1 through Big Sur. This section is just north of Wild Cattle Creek. Mud washed across the roadway from the cliffs in numerous locations along the 70+-mile stretch of this scenic coastal road.

California Coastal Highway 1 in Big Sur south of Rat Creek
A section of Highway 1 along the California coast in Big Sur with more examples of the numerous debris flows and mudslides that occur following a heavy rain. This section is just south of the Rat Creek debris flow that completely washed out a large chunk of the highway.

Big Sur, California Landslide - January 26 and 28, 2021
The storm that hit California’s coast between Jan. 26 and 28, 2021, blew out a portion of Hwy 1 near Big Sur. On Saturday, a USGS reconnaissance flight snapped this dramatic photo above the Rat Creek drainage showing the debris flow.

Fort Funston Structure-from-Motion point clouds
As part of the Remote Sensing of Coastal Change and Florence Supplemental projects we have been developing novel workflows for repeat-mapping of coastal environments at order decimeter resolution over up to hundreds of kilometers in a single day, using Structure-from-Motion photogrammetry or SfM, from crewed aerial platforms.

Collecting Water Samples
USGS samples water within wetlands to understand which environmental drivers impact carbon cycle and sediment accretion. Here USGS staff (Jennifer O'Keefe Suttles) pumps water from at Phragmites wetland, Mashpee, MA, to analyze at the Woods Hole Coastal and Marine Science Center Environmental Geochemistry lab.
