I is the best documented period of Navajo Canyon, beginning in AD 800 and lasting 200 years. "Pueblo II in Navajo Canyon is represented by the absence of Kana-a Black-on-white and the dominance of Black Mesa Black-on-white". Pueblo II (AD 900–1100) and early Pueblo III is the best documented cultural area in Lower Glen Canyon, corresponding with habitation on Cummings Mesa. Pottery includes mostly Tusayan varieties, Black-on-white, Black-on-red, and Red Wear Polychromes. Hopi people from the Jeddito area came into the canyons in the 14th century, represented by Yellow Wares, mostly Jeddito Black-on-yellow, and Jeddito plain. Most of the ceramic material found in the main canyon was probably made in the highlands, although it is possible some pottery was manufactured in Lower Glen Canyon. Clay deposits are found along the river, and some crude pottery specimens may have been made there. Only four burials were found in Lower Glen Canyon at three sites. Trash dumps are not very common at most sites. This is more evidence to suggest the seasonal rather than permanent occupation of hunters and farmers in the canyon. Cultural similarities are based on the presence or absence of certain types of ceramic wares. Group types of pottery, including Kayenta (Tusayan and Tsegi Orange Ware), Virgin (San Juan Red and White Wares), with Fremont, and Mesa Verde or Anasazi types of White and Desert Gray Ware, were found mostly on the right bank of the Colorado. Basketmaker II is characterized by a lack of pottery, as well as above-ground and underground cists lined with slabs. There is very little evidence of permanent occupation except at Talus Ruin, a small pueblo with a kiva, a ceremonial structure, made mostly of masonry, featuring jacal walls of sticks and reeds set in mortar in a single row of masonry. The presence of metates are evidence that campsites with slab-lined hearths were inhabited for longer periods. Agricultural structures are not found in the main lower canyon, and no formalized fields are found in the main canyon because of alleviation and slope wash burying. Houses, when found, are mostly sandstone slab with mortar, having one to seven rooms. "Well constructed mealing bins which usually denote permanency were lacking in the Lower Glen Canyon. In contrast, on Cummings Mesa at Surprise Pueblo, there was one entire room devoted to mealing bins…". In the highlands, granaries were near or incorporated into permanent pueblos, compared with
