The
Rhododendron: Nature's thermometer
Rhododendron can be called "Nature's thermometers." At 26 degrees, their leaves curl.
Pictured above are curling Rhododendron (temperature at Fallingwater was a windy 11 degrees when taken) found throughout the grounds of Fallingwater's home in Bear Run.
Since 1963 this 5,000-acre natural area has been owned and protected by Western Pennsylvania Conservancy. It lies along the west slope of Laurel Ridge, facing the spectacular Youghiogheny River gorge. The waters of Bear Run cascade through rhododendrons, past old-growth hemlocks, and over rocks and boulders producing a spectacular array of rapids and waterfalls. More than 20 miles of marked trails traverse an area of great natural diversity -- from the beauty and solitude of dense oak and hemlock forest to the sparkling-clear waters of Bear Run and Laurel Run. The Fallingwater grounds are adjacent to the nature reserve further fulfilling the tie between this world-famous Frank Lloyd Wright structure and the natural world.
A trip to Bear Run Nature Reserve is a rich outdoor experience in any season of the year. You are welcome to use the trails for hiking, nature study, photography, backpack camping, ski touring - or just to be alone for awhile.
