Glacial Features and Sediments

Glacial features and sediments are a testament to the region's geological history, particularly in the Okanagan Valley. The valley was carved out by glaciers during the Pleistocene era, which ended about 11,700 years ago. The glaciers scoured the landscape, creating U-shaped valleys, glacial lakes, and leaving behind a trail of sediments. The sediments, known as glacial till, are a mixture of rocks, soil, and other debris that were picked up by the glaciers as they moved. These sediments were then deposited in a new location, often at the foot of the glacier or in a glacial lake. The glacial till in the Okanagan Valley is composed of a variety of rocks, including granite, basalt, and sandstone, which were derived from the surrounding mountains. The sediments also contain fossils of plants and animals that lived in the region during the Pleistocene era, providing valuable information about the region's paleoenvironment. In addition to glacial till, the Okanagan Valley also features other glacial landforms, such as drumlins, eskers, and kames. Drumlins are elongated, teardrop-shaped hills that were formed when the glacier pushed rocks and soil ahead of it. Eskers are long, sinuous ridges that were formed when meltwater from the glacier deposited sand and gravel in a tunnel or pipe. Kames are small, rounded hills that were formed when meltwater from the glacier deposited sand and gravel in a depression. These glacial landforms are an important part of the region's geological heritage and provide valuable insights into the region's history.
