Flow was from bottom left. Map is ~1,600 km (990 mi) wide; the system extends south another 1,200 km (750 mi) to Echus Chasma. Coordinates 24°36′N 65°00′W / 24.6°N 65.0°W / 24.6; -65.0 Naming "Mars" in Japanese The **Kasei Valles** are a giant system of [canyons](/source/Canyon) in [Mare Acidalium](/source/Mare_Acidalium_quadrangle) and [Lunae Palus](/source/Lunae_Palus_quadrangle) quadrangles on [Mars](/source/Mars), centered at 24.6° north latitude and 65.0° west longitude. They are 1,580 km (980 mi) long and were named for the word for "Mars" in Japanese.[1] This is one of the largest [outflow channel](/source/Outflow_channel) systems on Mars. ## Geography Area around the Northern Kasei Valles in [Mars Express](/source/Mars_Express) images This huge system is 300 miles wide in some places. In contrast, Earth's Grand Canyon is only 18 miles wide.[2] It is one of the longest continuous [outflow channel](/source/Outflow_channel) systems on Mars. The Kasei Valles system begins in [Echus Chasma](/source/Echus_Chasma), near [Valles Marineris](/source/Valles_Marineris). It runs initially northward, then turns eastward and appears to empty into [Chryse Planitia](/source/Chryse_Planitia), not far from where [Viking 1](/source/Viking_1) landed. At around 20° north latitude the system splits into two channels, called Kasei Vallis Canyon and North Kasei Channel.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*] These branches recombine at around 63° west longitude, forming a large island between the channels known as [Sacra Mensa](/source/Sacra_Mensa). Some parts of the Kasei Valles are 2–3 km deep.[3] Like other outflow channels, they were likely carved by liquid water, possibly released by volcanic subsurface heating in the [Tharsis](/source/Tharsis) region, either as a one-time catastrophic event or multiple flooding events over a long time period. Others have proposed that certain landforms were produced by glacial rather than liquid flow.[4] Three sets of enormous cataracts (dry falls) are present in the area between an "island" feature in the southern channel, Lunae Mensae, and the crater [Sharonov](/source/Sharonov_(Martian_crater)).[5][6] These cataracts, evidently carved during megaflooding events, have headwalls up to 400 m high[6] and are considerably larger than the largest terrestrial analog, [Dry Falls](/source/Dry_Falls).[5] They may have migrated over 100 km upstream subsequent to their initial formation.[5] ## Gallery - Map of [Lunae Palus quadrangle](/source/Lunae_Palus_quadrangle) with labels.
