<P> The Cascades extend northward from Lassen Peak ( also known as Mount Lassen ) in northern California to the confluence of the Nicola and Thompson rivers in British Columbia . The Fraser River separates the Cascades from the Coast Mountains in Canada , as does the Willamette Valley from the upper portion of the Oregon Coast Range . The highest volcanoes of the Cascades , known as the High Cascades , dominate their surroundings , often standing twice the height of the nearby mountains . They often have a visual height ( height above nearby crestlines ) of one mile or more . The highest peaks , such as the 14,411 - foot ( 4,392 m ) Mount Rainier , dominate their surroundings for 50 to 100 miles ( 80 to 161 km ) . </P>
