Geography
Bell and Dayton creeks in West Hills are several of the headwaters of the Los Angeles River that originate in the Northwest San Fernando Valley. The Los Angeles River itself begins at the confluence of Arroyo Calabasas (Calabasas Creek) and Bell Creek in Canoga Park. These and other small creeks supply stormwater and suburban runoff water to the Los Angeles River, and several are considered year-round creeks. Although the creeks are now channeled and run within concrete walls, they do form a significant urban wildlife landscape and contribute to the population of indigenous wildlife left within the San Fernando Valley.
Both Bell Creek and Dayton Creek in particular have received attention due to their headwaters origins inside the SSFL—Santa Susana Field Laboratory in the Simi Hills. The SSFL is mandated for an environmental cleanup due to its uses as a testing center for rocket and missile engines, nuclear reactor research and fuel reprocessing, and high technology defense systems. It was also the site of a partial nuclear core meltdown in 1959. Prominent contaminants include radionuclides, VOCs-volatile organic compounds, Chromium, Lead, Benzene, and other components of rocket engine fuel and cleaning compounds.

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)
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—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)
