Is the soil under your feet, more clay, sand, rock or silt? Q.8 of The Big Here Quiz

According to this map and accompanying Soil Survey of Essex County, the soil under my feet is Brookston clay or Brookston clay loam.

According to “The Physiography of Southern Ontario”, Essex County and the southwestern part of Chatham-Kent are situated within the physiographic sub-region referred to as the Essex Clay Plain – a broad till plain left after the recession of the glacial lakes - Lake Whittlesey and Lake Warren [pdf]

Judging by the very general answers given on Kevin Kelly's website to this question ("clay"), it would appear that most folks are generally unaware of the nuances of soil classification. Even Wikipedia is particularly thin on the topic of soil.
