Summary

DescriptionClose view of a channel.jpg	English: NASA wrote the following caption: This channel is located within a large valley in the Northern Arabia Terra region of Mars. The channel is several thousand kilometers long and continues westward where it terminates in a depression on the surface. The valley containing this channel measures 1.5 km across, while the channel itself spans just 200 m. Several rock layers are visible along the channel walls, and dunes fill the channel floor. The channel cuts back and forth across the valley floor, which suggests surface water was present in the valley over long time periods. Written by: Ginny Gulick (20 July 2023)
