Elwha River Still Changing Five Years After World’s Largest Dam-Removal Project: More than 20 million tons of sediment flushed to the sea
Starting in 2011, the National Park Service removed two obsolete dams from the Elwha River in Olympic National Park, Washington. It was the world’s largest dam-removal project.

Global Study of World’s Beaches Shows Threat to Protected Areas
A first-of-its-kind survey of the world’s sandy shorelines with satellite data found that they have increased slightly on a global scale over the past three decades but decreased in protected marine areas, where many beaches are eroding.
Sea Level Rise Could Double Erosion Rates of Southern California Coastal Cliffs
Coastal cliffs from Santa Barbara to San Diego might crumble at more than twice the historical rate by the year 2100 as sea levels rise. U.S. Geological Survey scientists combined several computer models for the first time to forecast cliff erosion along the Southern California coast.
Scenic Hwy. 1 to reopen — 547 days after you could last drive the coast to Big Sur
