The basin then filled with Precambrian and Cambrian sediment which was eroded to form stream valleys over the next 550 million years. Glaciation then hollowed out the basin over the last 1.5 million years.Glacial scouringhttp://www.msstate.edu/dept/geosciences/CT/TIG/WEBSITES/LOCAL/Spring2002/Michael_Marsicek/images/Great_Lakes_Formation.gifGoogle Earth: Finger LakesGlacial reboundGlacial Dams & morainesThompson Glacier, Canadian Arctichttp://libwiki.mcmaster.ca/clip/index.php/Main/RecessionalMorainesAlluvial DamsLake Pepin, MNhttp://upload.wikimedia.org/wikipedia/commons/5/55/Mini_Alluvial_Fan_Imprinted_with_Footprints.jpgKettle pondshttp://earthobservatory.nasa.gov/IOTD/view.php?id=6034Gulf of Ob, RussiaGlacial Plunge basinsRound and Green Lakes, NYhttp://c0278592.cdn.cloudfiles.rackspacecloud.com/medium/620602.JPGOxbow lakesSturgeon River @Chassell, MichiganSink hole lakesWinter Haven, Floridahttp://www.swfwmd.state.fl.us/hydrology/sinkholes/SinkholePoster.gifFrost polygon lakeshttp://farm4.static.flickr.com/3392/3474214559_9a58e11299.jpgTectonic activityhttp://www.rockwalkpark.com/images1/localg2.jpgLake Timiskaming, CanadaVolcanic activityhttp://www.cen.ulaval.ca/pingualuit/CraterLakeRF2.jpgPingualuit Crater Lake, Quebec, CanadaBiological activityhttp://nogoodforme.filmstills.org/images/wallowingrhino.jpghttp://www.telegraph.co.uk/news/worldnews/northamerica/canadahttp://www.politicalworld.orgLake morphometry - DiversityLake morphometry -characterizationmorphometrylake erie: impacts on water qualityBathymetrycharacteristicsMaximum length (fetch)Maximum widthArea: hypsographic curvevolume( )3top bottom top bottomz A A A AV� + + +=Interactions with hydrologyDrainage lakesSeepage lakesDrainage lake: onondaga lake, new yorkSeepage lake: crystal lake,
