Though both Hoovers valued the restorative powers of nature, they were not averse to improving upon it. After choosing the Rapidan site, they carefully manipulated and enhanced its natural elements - terrain, boulders, water, and plantings. Their greatest natural artifice, Hemlock Run was created by diverting part of Laurel Prong so that its waters flowed through the heart of the camp in cascading layers, forming waterfalls and feeding the stocked trout pond. Their goal was to be sure every guest could hear the sounds of water from their cabins. From here you can take a lovely stroll out to what remains of the sluice the Marines constructed to fill Hemlock Run. To the sluice and back is a level walk of about 1/2 mile.
