RESTON, Va. — A new collaborative study led by the U.S. Geological Survey provides strong evidence that the Grand Canyon was carved out by spillover flooding from ancient Lake Bidahochi, a large lake fed by the ancestral Colorado River.  The lake’s eventual spillover likely helped establish the course of the Colorado River.

Researchers at the Georgia Cooperative Fish and Wildlife Research Unit are examining the short-distance movements birds make outside of migration. The researchers found these birds travel a lot less in areas with human activity, likely because they're able to more easily find shelter, food, and water.

Barrier islands—long, narrow strips of sand that line many coasts around the world—serve as a first line of defense against storms and rising seas. These dynamic landforms are heavily influenced by wind and waves, and new research suggests that seafloor features just offshore of barrier islands may play a bigger role in their survival than previously understood.

Episode 44 of lava fountaining at the summit of Kīlauea took place on April 9, 2026. Southerly/southwesterly winds resulted in the plume being transported in the north/northeast direction, resulting in tephra falling in areas of Hawaiʻi Volcanoes National Park, on Highway 11 nearby, and on communities near the summit of Kīlauea.
