we got a good view of another cliff dwelling, Oak Tree House.

This alcove had a sloping floor, so the people here built retaining walls and filled in behind them. This provided support for rooms, a work area, and a safe play area for children. This dwelling has an alcove within an alcove. They used every inch of the inner alcove space. Some of their buildings were four stories tall, reaching the roof of the inner alcove. Storage space was utilized on an upper ledge in the outer alcove.

Here's another preview of Sun Temple.
