Following the retreat of glacial ice, about 13 000 years ago, the lowlands were nearly completely flooded by the sea to a height of 30 m.

The Fraser River Lowland is a triangular area in southwestern British Columbia. The eastern apex of the triangle is at Hope, about 160 km inland from the Strait of Georgia. From here, the lowland broadens to the west to a width of about 50 km. The international boundary between British Columbia and Washington State crosses the southwestern part of the lowland. The Coast Mountains form the northern boundary of the delta-lowland. The Fraser River Lowland is the largest area of level land with suitable agricultural soils in coastal British Columbia.

Kettle Valley is a dry, forested area in the Okanagan Highland of southern BC. The name relates either to rock formations in the waterfalls at the confluence of the Kettle and COLUMBIA rivers in Washington state or to the shape of baskets woven by Salish people there.

The Okanagan Valley is in south-central British Columbia, extending about 200 km north from the American border.

The Rocky Mountain Trench is a long and deep valley extending approximately 1,500 km from the Bitterroot Valley in northwest Montana through British Columbia to the Liard Plain just south of the Yukon Territory. Its predominantly flat floor is 3–20 km wide and ranges in elevation between 600 m and 1,000 m above sea level. With walls made of sedimentary, volcanic and igneous rock, the Trench is sometimes referred to as the “Valley of a Thousand Peaks” because of the towering mountain ranges on either side: the Rocky Mountains to the east and the Columbia, Omineca and Cassiar mountains to the west. Humans have relied on the rich resources provided by this distinctive landscape from pre-colonial times to the present.
