The Arcadia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The quadrangle is located in the north-central portion of Mars’ western hemisphere and covers 240° to 300° east longitude (60° to 120° west longitude) and 30° to 65° north latitude. The quadrangle uses a Lambert conformal conic projection at a nominal scale of 1:5,000,000 (1:5M). The Arcadia quadrangle is also referred to as MC-3 (Mars Chart-3).
The southern and northern borders of the Arcadia quadrangle are approximately 3,065 km and 1,500 km wide, respectively. The north to south distance is about 2,050 km (slightly less than the length of Greenland). The quadrangle covers an approximate area of 4.9 million square km, or a little over 3% of Mars’ surface area.
Several features found in this quadrangle are interesting, especially gullies which are believed to be caused by relatively recent flows of liquid water. Dark slope streaks and dust devil tracks can have a striking appearance.

Famous quotes containing the word arcadia:
“To value the tradition of, and the discipline required for, the craft of fiction seems today pointless. The real Arcadia is a lonely, mountainous plateau, overbouldered and strewn with the skulls of sheep slain for vellum and old bitten pinions that tried to be quills. It’s forty rough miles by mule from Athens, a city where there’s a fair, a movie house, cotton candy.”
—Alexander Theroux (b. 1940)
