After returning to the canyon floor, I began walking from Klin Kletso, past the small Casa Chiquita site, northeast up the desert center of Chaco Canyon. At one point, I walked by a number of art panels on the canyon wall. Greasewood and saltbrush are the primary vegetation in the canyon. Chacoans used saltbrush for digging sticks and ate their seeds. Saltbrush is used by the Navajos to make a bright yellow dye. Near the end of the trail, I had to cross Chaco Walsh and there was some water in the bottom of it. Just before climbing up to the canyon rim, I saw the supernova panel. On the highpoint above the canyon, is Penasco Blanco, an oval great house complex. Penasco Blanco is unexcavated and located at spot with vast views in all directions. In this setting, the desolate ruins have a profound, lonely beauty. I stopped in the ruins to eat lunch. This beautiful place will always be with me.
