Haeckel, and a mile beyond again rises several hundred feet higher, though not quite so sharply, forming the peak called Mt.

"[6] This mountain is named for Alfred Russel Wallace (1823–1913), a British naturalist, explorer, geographer, anthropologist, and biologist who is best known for developing the theory of evolution contemporaneously with Darwin.

As fronts approach, they are forced upward by the peaks, causing them to drop their moisture in the form of rain or snowfall onto the range (orographic lift).
