Five distinct soil horizons, separated by loess, have been described from Bermuda by Sayles (40). The soils have been attributed to mild humid interglacial conditions, while the loess is considered to be due to the severe, windy periods of glacial advance.

Lacustrine soils are derived from ancient glacial lakebeds. These soils are higher in silt or clay content than other glacial soils, resulting in higher waterholding capacities, lower drainage and higher fertility. Lacustrine soils are more susceptible to erosion than till or outwash because of their fine texture.
Soil friction angle is a shear strength parameter of soils. Its definition is derived from the MohrCoulomb failure criterion and it is used to describe the friction shear resistance of soils together with the normal effective stress.

finetextured, low permeability, glacial till soils like those commonly found in the Greater Toronto Area and southern Ontario? 2. Should stormwater infiltration practices be designed differently when they are to be located on finetextured, low permeability soil?
A layer of grey clay was encounted at the end of a test pit. It was hard enough that it did not allow inserting the Torvane into the soil (as if it is an extremely weak rock).How could one undrstand if the clay is overconsolidated by such observation without an oedometer test.

Ice and its meltwater are the most important deposition agent for soil parent material in Canada. The last ice age occurred during the Pleistocene epoch, starting about 2 million years ago and ending about 10,000 years ago. During the ice age, there was a series of glacial advances and retreats.
Mined from glacial deposits, Glacial Rock Dust contains a broad range of trace minerals essential for healthy soil. These minerals are often depleted in soil over time. Glacial Rock Dust helps restore these mineral imbalances. Glacial Rock Dust improves soil structure, moisture retention, nutrient availability, and microbial action.
