where does the cascade range start and end
Cascade Range 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 [2], 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,[3] 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).
Uwharrie Mountains The Uwharries were once a coastal mountain range;[citation needed] isostasy has slowly raised the eastern seabed until today they lie in the Piedmont of North Carolina over 150 miles from the coast. Formed approximately 500 million years ago by accretion along the Gondwanan tectonic plate, they are thought to have once peaked at some 20,000 feet,[2] before eroding to a maximum of just over 1,100Â ft. The range's high point is High Rock Mountain (1,188 feet/362 meters as measured by the NC Geodetic Survey), in southwestern Davidson County.
