On entering the lake, where the stream runs southeasterly, and for some time before, we had a view of the mountains about Ktaadn, (Katahdinauquoh one says they are called,) like a cluster of blue fungi of rank growth, apparently twenty-five or thirty miles distant, in a southeast direction, their summits concealed by clouds. Joe called some of them the Souadneunk mountains.Henry David Thoreau, The Maine Woods, 1864
