Punctuating the plateau are several prominences of land including Little Mountain (a dormant volcano, approximately 170 metres above sea level) in Vancouver, and Capitol Hill (approximately 220 metres) and Burnaby Mountain (home to the main campus of Simon Fraser University; approximately 380 metres) in Burnaby. The plateau is flanked at its eastern end by the Coquitlam River, which flows south from Coquitlam Lake on the mainland into the Fraser River, its mouth lying upstream from the Brunette River. The land east of the Coquitlam River is largely flat and lying close to sea level, except for the stand-alone rise of Mary Hill in Port Coquitlam (approximately 70 metres).
