The "fort" wall, part of which is shown here, was 280 feet long and seven feet at its greatest height. Note the porous nature of the volcanic rock. 84 Wisconsin Academy of Sciences, Arts and Letters [Vol. 44 Despite my calling this site a fort, it was probably not used as such. The wall did not stand above the ground level, but appeared as a stone facing for the tOp edge of a steep-sided mesa. There was no protection from the mesa side, which would have been most vulnerable to attack. These facts preclude any protection from this mortarless masonry. What then was this structure? My guess is that it was built by a family who took pride in their building craft, and who used their skill to protect the mesa rim on which the dwelling perched. The building was probably built on this site because it was near several meadows and because of its commanding view. Today water and fuel would be as easy to procure had the dwelling been built a short distance from the canyon rim where no earth-supporting walls would be needed. It may have been otherwise in the days of the builder. On another occasion, while attempting to photograph some wild flowers near our camp site, I climbed a fallen tree in order to get an overhead view of the blossoms. From a height of about 6 feet I noticed through the reflex lens of my camera that stones near the flowers were arranged in a crude circle about 50 feet in diameter, with other rows of stones radiating from the center to
