| When we talk about history we usually focus on the past of humans, but nature has a history too – and sometimes it’s surprising. Take, for instance, Maple Flats seasonal ponds in southeastern Augusta County. Maple Flats ponds are areas of land underlain by dolomite (a type of limestone) formed long ago. On top of the dolomite lies a deposit of more acidic quartzite weathered from the nearby mountains. Over time, the dolomite is dissolved by water, leading to its collapse and the formation of sinkholes. A layer of clay forms several feet below the surface and creates a perched surface water table that reaches up into the sinkholes during the wet season and causes a temporary pond to form. The Maple Flats Ponds Complex includes about 22 natural sinkhole ponds and has been the focus of scientific investigations since the 1930s. Maple Flats is home to a unique array of flora and fauna, some of which are not found anywhere else in Virginia. Scientists have identified a treasure trove of more than 90 species of vascular plants that are not normally found in the area and a few unusual species of critters too, like the eastern tiger salamander, wood frog, and fairy shrimp. Access the ponds on foot from Forest Road 42 (Coal Road). A nearby parking area is marked with big boulders. Picture Credit: Maple Flats Ponds Complex (photo by Meagan Bragg link) |
