“…But dates on this type of material from this region may be unreliable (CLAYTON and MORAN, 1982). Consequently we place the 18 ka margin at the Late Wisconsinan limit as proposed by FULLERTON and COLTON (1986) in Montana.…”

“…Useful and detailed critical appraisals and counter arguments can be found in DENTON and HUGHES (1981 ). Most workers on the American Plains (MICKELSON et al, 1983;CLAYTON and MORAN, 1982;FULLERTON and COLTON, 1986) do not accept Stalker's glacial limit in Alberta but place the Late Wisconsinan Laurentide margin far south in Montana. New England workers (see MICKELSON ef ai, 1983) favour much more extensive Laurentide ice in the Appalachians and Gulf of Maine than does GRANT (1977) or RAMPTON era/.…”

“…The margin of the Laurentide Ice Sheet changed little between 18 and 14 ka, although regionally important readvances of the lobes in the southern Great Lakes region culminated in moraine construction at 17.2,16.7 and 15.5 ka (MICKELSON et al, 1983) and the lobes in Montana readvanced at least four times before retreating to the international boundary (FULLERTON and COLTON, 1986). One of the largest ice marginal oscillations occurred during the "Erie Interstade" when the Erie-Ontario Lobe withdrew from a position near the Late Wisconsinan limit and retreated back to the Ontario basin allowing Lake Leverett to form just above the present level of Lake Erie in the Erie basin (MORNER and DREIMANIS, 1973).…”

AbstractEleven paleogeographic maps and a summary ice retreat map outline the history of advance, retreat, and readvances of the Laurentide Ice Sheet along with associated changes in proglacial drainage and relative sea level oscillations for Late Wisconsinan and Holocene times. The text outlines pertinent chronological control and discusses the paleoglaciology of the ice sheet, with attention to location and migration of ice divides, their attendant domes and saddles, and to ice streams, ice shelves, and mechanisms of déglaciation. At 18 ka the ice sheet consisted of 3 sectors with an interlocked system of ice divides joined at intersector saddles. A throughgoing superdivide is recognized and named the Trans Laurentide Ice Divide. The ice sheet retreated slowly from 18 to 13 ka, mainly along the west and south margins, but still held a near maximum configuration at 13 ka. A regional change in flow pattern over the Prairies just before 14 ka is thought to represent a large reduction in ice volume, but not in extent, and likely was triggered by a switch from nondeforming to deforming bed conditions. Retreat between 13 and 8 ka was vastly more rapid in the west than in the east, which resulted in eastward migration of the divide system of Keewatin Ice but relatively static divides of Labrador and Foxe Ice. By 10 ka the Trans Laurentide Ice Divide had been fragmented as Hudson Ice became increasingly autonomous. By 8 ka Hudson Ice had disappeared, little ice was left in Keewatin, but Foxe Ice still held its near maximum configuration and Labrador Ice was still larger than Foxe Ice. Repeated surging along aquatic margins and calving back of margins thinned by surging probably was the most important mechanism of deglaciation of Keewatin and Hudson Ice. The core of Foxe Ice disintegrated at 7 ka but retreat and readvance of Foxe Ice remnants continued throughout the Holocene.

“…Contrary to this age assignment, FULLERTON and COLTON (1986) state that "None of the vertebrate species in the Fort Qu'Appelle, Riddell, or Medicine Hat Sangamon' faunas is demonstrably diagnostic of a Sangamon interglacial (post-lllinoian and pre-Wisconsin) age". They suggest that the Riddell Member and correlated units at Medicine Hat should be tentatively correlated "with marine oxygen isotope stage 7 within the complex lllinoian glaciation".…”

“…Whereas some workers (Wagner, 1966;Mickelson et al 1983;Fullerton and Colton, 1986) conclude that the last Laurentide glacier actually coalesced with mountain piedmont glaciers in this area, others (Horberg, 1954;Alley. 1973;Stalker and Harrison, 1977) maintain that mountain glaciers advanced and partially or completely retreated prior to the advance of the corresponding Laurentide glaciers.…”

ABSTRACTPedological investigations in the Waterton Park area provide a useful means of testing subdivisions of Quaternary glacial deposits based on geomorphic relations. Soils in the region, however, including Podzols, Brunisols, Luvisols, and Chernozemics, also reflect the influence of soil forming factors other than time. Nonetheless, a chronosequence can be established by comparing time-diagnostic properties of soils on different geomorphic units in areas with similar climate, vegetation, slope and parent material. Properties thought to be most diagnostic of relative soil age include thickness and degree of clay buildup in B horizons and two soil development indices which average degree of development of a number of properties. Pédologie and geomorphic data suggest surface deposits include mountain tills of three or four separate advances and continental tills of two separate advances. Mountain tills are tentatively correlated with the Late Wisconsinan (about 18 ka BP), Late and or Early Wisconsinan (about 100 to 65 ka BP). Late lllinoian (about 200 to 132 ka BP). and Early lllinoian and/or pre-lllinoian (about 400 to 700+ ka BP), whereas continental tills are tentatively correlated with the Late Wisconsinan and Late lllinoian deposits of the U.S. Midcontinent.
