Qu'Appelle Valley Geolog Stop 8
- Lake Indian Head Plain
[ Previous Stop ] [ Next Stop ]
What is interesting about Stop 8 is the topography of the area. Stop 8 is surrounded by some of the highest quality soil in Canada. If it were not for ice being dammed and rerouted down the Pipestone Spillway (see diagram), the fields of Stop 8 would not exist. Rather than spreading across the plain and making the soil similar to others in the Qu'Appelle area, 15,000 years ago the glacier from Lake Indian Head melted down the Pipestone Spillway. This meltwater drained into Lake Souris, leaving the Indian Head lakebed flat, gently undulating, and nutrient-rich.
Underneath the soil is a large amount of silty clay. Because of the high clay content of these soils, Lake Indian Head Plain has the capability of storing large amounts of water in a form best for plant growth, resulting in good arable farmland.
