🌊 Harbor Wave, Ocean Pulse: The Science of Tsunamis from Seafloor to Shore
Some ocean hazards announce themselves with wind, foam, and a rising sky. A tsunami often does not. Far from shore, it may pass as a long, subtle lift, more like a slow breath than a breaking wave. Even the word “wave” can mislead, because a tsunami is not simply the surface…

🌫️ Mist Over Ancient Ridges: The Great Smoky Mountains as a Living, Breathing World
From section: 🌄 Roots in deep time: how the Smokies became mountains… During the Pleistocene Epoch, about 2.58 million to 11,700 years ago, colder climates influenced the region even though continental glaciers did not cover the Smokies directly. Freeze-thaw action fractured rock and helped create boulder fields and streamside stones that still record the work of ice-age climates.
