The glacial lake Agassiz

Paleohydraulics of the last outburst flood from glacial Lake Agassiz and the 8200BP cold event

“…At various times during its 5000 yr (4000 radiocarbon year) existence, overflow from Lake Agassiz was routed to the Mississippi-Great Lakes-St. Lawrence and Mackenzie drainage systems (Teller, 1990a, b;Licciardi et al, 1999;Teller et al, 2002) but only in the final stages was the barrier of the LIS breached and Lake Agassiz water routed northward to Hudson Bay. Key papers relating to Lake Agassiz and the ice-marginal fringe of proglacial lakes include those by Upham (1895), Johnston (1946), Elson (1967), Hardy (1977), Vincent andHardy (1977, 1979), Dredge (1983), Klassen (1983), Teller and Thorleifson (1983), Veillette (1994), Mann et al (1999), Marshall and Clarke (1999), Clark et al (2001) and Teller (2001).…”

Origin of the Herman–Norcross–Tintah sequence of Lake Agassiz beaches in Manitoba, Canada

“…These standlines include ridges of littoral sediment (beaches) and wave-eroded scarps that mark the extent of the lake at the time of abandonment. They were mapped in the late 19th century by Warren Upham (1890Upham ( , 1895, although his maps were at a large scale (1:380,000 or larger; see Fig. 2).…”

Changes in the Bathymetry and Volume of Glacial Lake Agassiz Between 11,000 and 9300 14C yr B.P.

“…The Lockhart Phase extended from about 11,700 to 11,000 14 C yr B.P., and the Herman beaches outline the extent of Lake Agassiz in the southern end of the basin at this time (Upham, 1895;Fenton et al, 1983;Hobbs, 1983). Drainage during the Lockhart Phase was through the southern outlet (Minnesota River Valley; e.g., Elson, 1967;Fenton et al, 1983) (Fig.…”
