Of the Great Pueblos in Chaco Canyon, D-shaped Pueblo Bonito, possibly five stories
tall along the outer arc, has the greatest number of rooms, estimated at 650. This view
is from the mesa to the North of the ruin. The center wall aligns to true North.

Fajada Butte is noted for the Sun Dagger hierophany, a petroglyph spiral behind slabs of rock which framed zenith passage sun and moon light as a unique, complex seasonal calendar. Below, an interactive display at Maxwell Museum, University of New Mexico, displays the change in illumination for each season. The slabs at the site recently shifted, likely studied to death!

The style of masonry varies at the various great houses in Chaco Canyon. All the masonry is of high quality. Nonetheless, the beautiful artistry was covered with stucco and probably painted. It is all the more impressive for having survived for 1,000 years in an exposed area.

After Chaco Canyon was abandoned the most important site in the San Juan Basin was Aztec Ruins. Later in the sequence Casas Grandes replaced Aztec as the largest center. Chaco Canyon's great houses, the various ruins at Aztec and Casas Grandes are aligned on a north-south meridian. I discovered this alignment in 1990 and named it the "Chaco Meridian" in 1991. Also on the Chaco Meridian is Mount Wilson, one of the highest peaks in the Rockies. Pueblo Bonito is located at precisely 1/200 of circumference from Mount Wilson.
