As we noted in January (see “Famed LeTort Spring Run Threatened by Sinkhole“), the local chapter of Trout Unlimited was preparing to organize an effort to find the source of the latest sinkhole to threaten the famed LeTort in central Pennsylvania. The good news is that the work has paid off. Check out the size of the hole they needed to dig to uncover the leaky bedrock. “Conservationists representing Cumberland Valley Trout Unlimited and LeTort Regional Authority, using donated equipment and materials, expected to go back to the site this morning to begin constructing a grout plug made of concrete and bentonite, a clay-like substance that expands when wet.” David Blymire in the Carlisle, Pennsyvlania Sentinel.
