This ruin is situated on the San Juan about 3 miles below the sandy
bed of the mouth of the Montezuma, on a bluff 50 feet above the river.
The ground plan by Jackson[21] indicates a building shaped like a
trapezoid, 158 feet on the northeast side, 120 on the southeast, and
32 on the northwest side. The southwest side is broken midway by a
reentering area at the rim of the bluff over the river.

In the center of this trapezoidal structure there is represented a
series of rooms arranged like those of Horseshoe House, but composed
of a half-circular chamber surrounded by seven rooms between two
concentric circular walls. Thus far the homology to Horseshoe House is
close but beyond this series of rooms, following out the trapezoidal
form, at least five other rooms appear on the ground plan. The position
of these recalls the walls arranged around the tower at Mud Spring
village. In other words, the ruin resembles Horseshoe House, but has
in addition rectangular rooms added on three sides, forming an angular
building. So far as the author’s information goes, no other ruin of
exactly this type, which recalls Sun Temple, has been described by
other observers.
