This image, taken by NASA 2001 Mars Odyssey spacecraft, shows the western wall of Uzboi Vallis near the intersection of the vallis and Holden Crater. Many channels dissect the wall of the channel.

Today's VIS image shows a small section of Uzboi Vallis. This valley system arises just north of Argyre Planitia and flows northward into Holden Crater. Uzboi Vallis is 366km long (227 miles).

This image from NASA Mars Odyssey spacecraft captures two channels Nirgal Vallis is the smaller sinuous channel on the left and Uzboi Vallis is the larger channel located in the lower right and Luki Crater located in the upper right.

This image from NASA Mars Reconnaissance Orbiter shows layered deposits in Uzboi Vallis which sometimes occur in alcoves along the valley and/or below where tributaries enter into the lake from surrounding clay-bearing surfaces. http://photojournal.jpl.nasa.gov/catalog/PIA21563

Today's VIS image shows a small section of Nirgal Valles (left side of image) just where it flows into the larger Uzboi Vallis (right side of image). Located in Noachis Terra, Nirgal Valles is 610km long (379 miles), and arises in Noachis Terra. Uzboi Vallis is 353 km long (219 miles) and arises just north of Argyre Planitia and flows northward into Holden Crater. While shorter than Nirgal Valles, Uzboi Vallis is much wider.

This image from NASA 2001 Mars Odyssey shows a delta deposit on the floor of Holden Crater. This delta was formed by small channels dissecting the rim of the crater, rather than the influx of material from Uzboi Vallis.

This VIS image shows the two channel segments of Nirgal Vallis that join just off the image to the east (right). Arising in Noachis Terra, the eastward flowing Nirgal Vallis is 610 km long and empties into Uzboi Vallis.
