The cliffs are over three hundred feet high and the villages are similar to Mesa Verde of Colorado, and as unaccessible, as impregnable to attack.
"Black Man's Burden"
Dallas McCord Reynolds
So as whosoever shall first possess it, it shall be found unaccessible for any enemy, except he come in wherries, barges, or canoas, or else in flat-bottomed boats; and if he do offer to enter it in that manner, the woods are so thick 200 miles together upon the rivers of such entrance, as a mouse cannot sit in a boat unhit from the bank.
"The Discovery of Guiana"
Sir Walter Raleigh
And clothest Mathesis in rich ornaments, That admirable mathematic skill, Familiar with the stars and Zodiac, To whom the heaven lies open as her book; By whose directions undeceivable, Leaving our Schoolmen's vulgar trodden paths, And following the ancient reverent steps Of Trismegistus and Pythagoras, Through uncouth ways and unaccessible, Doth pass into the pleasant spacious fields Of divine science and philosophy, etc.
"Shakespeare's Lost Years in London, 1586-1592"
Arthur Acheson
