Waterfall on Broad River
Kevin Adams' book mentions a waterfall he saw in a postcard photo, being described as in the "Broad River Gorge". Could this be it? Aerial photos seem to confirm the presence of a waterfall, and a road called "Hemlock Falls Road" is just downstream. Check the Photos link below to see an oblique view of this section of the river in Bing Maps. It's hard to tell, but it appears that there is a waterfall there.
This waterfall is located on private property and is inaccessible to the public.
