The McKenzie Pond Boulders are actually not even near McKenzie Pond. They are in the forest north and east of McKenzie Pond Road. They are now famous among "boulderers" (those who climb boulders) and even have at least one web page devoted to them (see
http://www.newenglandbouldering.com/media/McKensieGuide.pdf ); but when I first saw them (I am not a boulderer), back in the mid-1970s, only a handful of local people knew of their existence. They are an amazing community of forms and have very compelling energy. The Adirondack Mountains are rich in great boulder assemblages, of which this is but one -- its popularity enhanced, no doubt, by its accessibility between the villages of Saranac Lake and Lake Placid.
