Geography
The San Antonio Springs are located about three miles (5 km) north of Downtown San Antonio; most are now on the property of the University of the Incarnate Word in Midtown San Antonio. The springs are fed by water from the Edwards Aquifer; this water reaches the surface through faults along the Balcones Escarpment. There have been more than 100 individual springs identified, but many of these are no longer active due to pumping demands on the Edwards Aquifer and sedimentation from the upstream Olmos Creek. During periods of drought, the springs sometimes stop flowing entirely, only to resume when water levels rise in the aquifer. The mean flow from the springs is 20 ft³/s (0.6 m³/s).

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)
“The California fever is not likely to take us off.... There is neither romance nor glory in digging for gold after the manner of the pictures in the geography of diamond washing in Brazil.”
—Rutherford Birchard Hayes (1822–1893)
“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)
