The author’s limited visit to this region made it impossible to record
all the various shapes of eroded pinnacles bearing buildings found in
Hill Canyon, but one of the most remarkable of these foundations was
observed to lean very perceptibly to one side (pl. 13) so that one side
of the ruin barely falls within the line of stable equilibrium. The
top of this leaning pinnacle was inaccessible, the height being about
50 feet from the base, which rose from a narrow ridge over 200 feet
above the plain. The author’s idea of the ground plan and character
of the masonry in this ruin is limited to what could be seen from the
road, but its general appearance from that distance is the same as the
preceding ruin.
In this account the author has mentioned a few of the more prominent
mushroom rock ruins, confining himself to those which can be observed
in a hurried visit to the canyon. It is undoubtedly true, as reported
by several cowboys, that the side canyons, difficult of access,
concealed many others which a longer visit would bring to light. The
characteristics of the ruin crowned pinnacles, or leaning buttresses of
rock in Hill Canyon are shown in plate 13.
