Sunday

From NASA's Image of the day: "The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this view of the Chesapeake Bay region as the clouds were clearing on December 20. The snow highlights the courses of the Potomac and Susquehanna Rivers from the Appalachian Mountains to the Chesapeake Bay. The ridges and valleys of the Appalachian Mountains are similarly highlighted. The forested peaks are darker than the snow-covered valleys."
