On Thursday, March 6, birders (left) bundled in many layers braved below-freezing temperatures at Riley's Lock in Potomac to look out at 1,000 water birds, many of them unusual to the upper Potomac River. Two days later, with temperatures in the 60s and sunny weather on Saturday, March 8 providing a welcome contrast to ice, snow and low temperatures near zero just a few days before, many people in Potomac took to the outdoors, like this stand-up paddle boarder (right) on the Potomac River at Riley's Lock. With water temperature in the river at 41 degrees, however, the wetsuit was essential.
