Importance of the Rossendale Site in establishing a deglacial chronology along the southwestern margin of the Laurentide Ice Sheet
of ostracods, molluscs, and the dated moss all support a young deglacial scenario. The ice margin appears to have retreated into the southern Lake Agassiz basin after 12 000 yr B.P. and north of the Rossendale site by 11 000 B.P. About 10 000 yr B.P., following

The Minnesota tunnel valleys are composed of individual segments 10-20 km long, and the segments commonly terminate in subaerial outwash fans at recessional ice margin positions. Eskers, associated with the tunnel valleys, are also composed of short
and McLean must also be considered younger than previously thought. The persistence of the Laurentide Ice Sheet margin on the central Labrador coast until 7 600 yr ago probably restricted the northward movement of early prehistoric people into northern
indicates that the ice margin of the Lake Michigan lobe must have retreated at least as far north as the Straits of Mackinac region during the Mackinaw Interstade.
Apart from an introduction into the historical development of urbanisation in Latin America, this book deals with the problems of barrios (marginal areas, shanty towns), housing programmes for the poor, and the perspectives of the informal sector
Recent investigation of raised fields and canals in various wetlands of lowland Mesoamerica indicates that they were manmade and were used some time in the past to produce a variety of crops. The fields were on the margins of wetlands with repeated
