Geography
Originally, Tempe Butte was part of a series of horizontal layers, but through tilting of the strata by the isostatic formation of South Mountain, and millennia of erosion created the distinctive hogback of resistant andesite, over sedimentary deposits and rhyolite beds.
Despite intensive development, the butte and its immediate surroundings continue to support a variety of native vegetation, including saguaro, Buckhorn Cholla, barrel cactus, creosote bush, palo verde, and mesquite. Native wildlife include jackrabbits, and small desert-adapted species such as pack rats.

Famous quotes containing the word geography:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.”
—Ralph Waldo Emerson (1803–1882)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
