Bidahochi Formation
http://dbpedia.org/resource/Bidahochi_Formation an entity of type: SpatialThing
The Pliocene to Late Neogene Bidahochi Formation lies at an elevation of about 6,300 feet (1,920 m) to 6,600 feet (2,012 m) at the southeast of the Colorado Plateau; the deposits are from Hopi Lake (also called Bidahochi Lake), and the deposits extend southwards to the region at the north perimeter of the White Mountains of central-east Arizona. Bidahochi Lake is thought to have been a single "large lake, or several shallow, and ephemeral ones." Various fossil types are found; also bird trackways.

The Pliocene to Late Neogene Bidahochi Formation lies at an elevation of about 6,300 feet (1,920 m) to 6,600 feet (2,012 m) at the southeast of the Colorado Plateau; the deposits are from Hopi Lake (also called Bidahochi Lake), and the deposits extend southwards to the region at the north perimeter of the White Mountains of central-east Arizona. Bidahochi Lake is thought to have been a single "large lake, or several shallow, and ephemeral ones." Various fossil types are found; also bird trackways. The Bidahochi Formation contains basalt flows that form an erosional protecting unit above the highly erodable Chinle Formation. The Bidahochi Formation extends approximately 112 miles north–south, or north-northwest by south-southeast, a length approximately equivalent to today's Great Salt Lake of Utah. The Bidahochi is possibly the only extensive nonvolcanic Neogene formation of the Colorado Plateau. It has been studied by geologists for clues to conditions on the plateau during this time interval and to test hypotheses for the initial incision of the Grand Canyon
