Young Fluvial Channels in Margaritifer Terra

Margaritifer Terra is the most impressive water-modified landscape on Mars that preserves the highest density of valley networks on the planet. Fluvial activity began in the Noachian period, likely peaked in the late Noachian-to-Hesperian, and then persisted, at least locally, into the Late Hesperian or Amazonian epoch. (This time period goes back at least 4 billion years to the present.) Our image shows fluvial channels that cut through the ejecta from Jones Crater, indicating relatively younger water activity in the region. https://photojournal.jpl.nasa.gov/catalog/PIA25360
