The Pueblo del Arroyo is the second or third largest building in Chaco Canyon, depending on how it is figured. It was built between 1025 and 1125, fairly late in the Chaco building period. Thus, it was not in use very long.

It had 280 rooms and 20 kivas. It was four stories high in some places. It was generally semicircular or "D" shaped, with dimensions in both directions over 200 feet.

I do not know the function of the rocks in the foreground. They are near a kiva, but don't seem to be a part of it. I just used them to tie down the foreground of the picture.
