The San Rafael Swell is a large geologic feature located in south-central Utah, USA about 30 miles (50 km) west of Green River, Utah. The San Rafael Swell, approximately 75 miles (121 km) by 40 miles (64 km), consists of a giant dome-shaped anticline of sandstone, shale, and limestone that was pushed up during the Paleocene Laramide Orogeny 60-40 million years ago. Since that time, infrequent but powerful flash floods have eroded the sedimentary rocks into numerous valleys, canyons, gorges, mesas and buttes. The Swell is part of the Colorado Plateau physiographic region.

Famous quotes containing the words san and/or swell:
“the San Marco Library,
Whence turbulent Italy should draw
Delight in Art whose end is peace,
In logic and in natural law
By sucking at the dugs of Greece.”
—William Butler Yeats (18651939)
“And we may be led, then, upward through more
Powerful forms of poetry, past columns
With peeling posters on them, to the country of indifference.
Meanwhile if the swell diapasons, blooms
Unhappily and too soon, the little people are nonetheless real.”
—John Ashbery (b. 1927)
