Fluctuations in waterlevels and a later glacier advance into the Dundas Valley causeda series of lower lake levels to result, including Lakes Wayne,Warren, Grassmere, and Lundy. These lakes resulted in thedeposition of deltaic sands at Brantford and large amounts ofdeep water silt and clay in South Dumfries, Brantford, Onondaga,and Tuscarora Townships (Figure 4) . Final drainage ofglacial lake waters in Brant County was effected approximately12,000 years ago . Since that time, alluvial sedimentshave continuously been laid down along the major watercourses and soil development has progressed .12Physiography and Sediments and Their Relationship toSoils of the CountyThe distribution of the principal soil forming glacial sedimentsis shown in Figure 4 (5) . Of the tills shown in Table 4,only the Port Stanley and Wentworth tills are common at thesurface, while the Catfish Creek and older tills only occur indeep exposures or locally as small inliers . Lithology of the surfacetills is given in Table 4 .The Catfish Creek till is a very hard grey to yellowishbrowntill, occurring as buried ground moraine for the mostpart . Where it is exposed, its thickness ranges from 0 .5 to 10metres . At the surface it is very similar to the Wentworth tilland may be present as inhers within the units mapped asWentworth .

It ranges from 1 to10 metres in thickness and is usually a grey colour which oxidizes to brown or yellowish-brown. Strong leaching is presentto a depth of 20 to 40 cm but is locally greater than this . Thepebble lithology generally reflects the underlying dolomiticterrain with a strong influence of limestone transported fromthe south and southeast . The fine texture of this till makes itsusceptibleto frost heaving .Muriel, Gobles and Kelvin soils have developed onthe siltyclay loam Port Stanley till . Where sand blankets the till to adepth of 40 to 100 cm, till phases of the Bookton, Berrien andWauseon soils are mapped . The relationship of these soils onthe Tillsonburg moraine near Harley, to adjacent lacustrineand eolian sands, is shown in Figure 5 .The Wentworth till (Table 4) is strongly dolomitic withmuch of the dolomite of Guelph-Lockport affinity. This tilloccurs primarily in the Paris, Galt, and Moffat moraines. It isgenerally yellowish-brown in colour and ranges from 3 to morethan 20 metres in thickness . In the Paris moraine and southernpart of the Galt moraine the till is frequently thin overlyingsand and gravel . Drumlins in Tuscarora Township and associatedsmall patches of ground moraine are correlated with theWentworth till, though texturally finer. Greater limestone contentoccurs in the pebble lithology in this area due to transportfrom the Bois Blanc and more southerly limestone units .Dumfries soils have developed on hummocky landformsand Guelph and Woolwich soils on undulating or rolling areasthroughout much of the Galt and Paris moraines .
