Glaciofluvial gravel and sand, southern British Columbia
This small cliff (about 3 metres high) offers a cross-sectional view of well layered/stratified/bedded sand and gravel (pebbles, cobbles and boulders) deposited by a high-energy braided river during Late Quaternary deglaciation. (This is a common scenario in the recent geological history of Canada, and elsewhere: as the glaciers melted back, they released large quantities of coarse sediment, and the rivers of meltwater transported and deposited gravel and sand in bars and channels.) Location: near the town of Midway and the USA border in southern B.C., western Canada.
