The general height of the mountain-range on Vancouver Island is from 2000 to 3000 ft.; some peaks are 6000 ft.; and Victoria Peak is 7484 ft.
The alpine treeless region occupies only the upper flanks of the spinal mountain-range above an elevation varying from 1800 ft.
The warm winds which sweep up the Mississippi Valley from the Gulf of Mexico are responsible for the extremes of heat, and the Arctic winds of the north, which find no mountain range to break their strength, cause the extremes of cold.
It is a strip of land narrow at the north end and widening out towards the south, consisting roughly of the continuation of the mountain range which bounds central Siam on the W., though the range appears in certain parts as no more than a chain of hillocks.
The southern half on the other hand is covered by a mountain range whose chief peaks are situated along the southern border, namely Halimun mountain, the volcanoes Salak, Pangerango and Gede, and the Megamendung.
