This is more evidence to suggest the seasonal rather than permanent occupation of hunters and farmers in the canyon.Д¬ultural similarities are based on the presence or absence of certain types of ceramic wares. Trash dumps are not very common at most sites. Only four burials were found in Lower Glen Canyon at three sites. Clay deposits are found along the river, and some crude pottery specimens may have been made there. 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. 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.Pottery includes mostly Tusayan varieties, Black-on-white, Black-on-red, and Red Wear Polychromes. Pueblo II (AD 900вЂ“1100) and early Pueblo III is the best documented cultural area in Lower Glen Canyon, corresponding with habitation on Cummings Mesa.' 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 I is the best documented period of Navajo Canyon, beginning in AD 800 and lasting 200 years. The pottery types are Kana-a Black-on-white, Deadmans Black-on-red, and Kana-a Gray, made from deposits found in Lizard Alcove. Pueblo I Era (AD 750вЂ“900) remains are found at Rock Creek in Lower Glen Canyon, and in Navajo Canyon.The Basketmaker culture is believed to have lasted later than Pueblo I. :вЂЉ62 Basketmaker III introduced fired pottery, mostly Lino Black-on-gray and Lino Gray, and some small amounts of Lino Fugitive Red and Obelisk Gray. Basketmaker III is not found in the Lower Glen Canyon, but is documented in Navajo Canyon, a large left bank tributary of the Colorado River, within the geographical area of the Lower Glen Canyon. Radiocarbon dates from charcoal material span the period between AD 250 and 440 (plus or minus 80 years). A Late Basketmaker II Era (generally AD 50вЂ“500) is represented by several sites.1 to the 15th century and recorded history from 1776 to the present'. Studies indicate a chronology for the Lower Glen Canyon prehistory, 'from pre-A.D. Department of the Interior within Glen Canyon National Recreation Area.Д«efore the Glen Canyon Dam Prehistoric cultural periods Today, Glen Canyon and Lake Powell are managed by the U.S. Beginning in the late 1990s, the Sierra Club and other organizations renewed the call to dismantle the dam and drain Lake Powell in Lower Glen Canyon. :вЂЉ526 The Glen Canyon Dam remains a central issue for modern environmentalist movements. Contrary to popular belief, Lake Powell was not the result of negotiations over the controversial damming of the Green River within Dinosaur National Monument at Echo Park the Echo Park Dam proposal was abandoned due to nationwide citizen pressure on Congress to do so. In 1966, a reservoir, Lake Powell, was created by the construction of the Glen Canyon Dam, in the Arizona portion of Glen Canyon near Page, inundating much of Glen Canyon under water hundreds of feet in depth. Like the Grand Canyon further downstream, Glen Canyon is part of the immense system of canyons carved by the Colorado River and its tributaries. A small part of the lower end of Glen Canyon extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Glen Canyon starts where Narrow Canyon ends, at the confluence of the Colorado River and the Dirty Devil River.

Glen Canyon is a natural canyon carved by a 169.6-mile (272.9В km) length of the Colorado River, mostly in southeastern and south-central Utah, in the United States.
