About this image

This false color image shows part of Harris crater (center of image) and an unnamed crater (top of image). These craters are located north of Hellas Planitia. At the upper right part of the Harris Crater rim, there is a fan shaped form. Fans can be created by different processes. Delta deposit fans are created under water, when a river flow slows down and drops sediments from the water column. These sediments are typically fine grained silts. Deltas form over time and can take many shapes as the river changes channels. The Mississippi River delta is formed this way. Alluvial fans are created in dry climates with short fluid seasons. In this case a single stream hits a topographic opening (think ravine) and sheds the rocks and sand down hill. The alluvial fan shape is created from the single opening. Either way, fans form by the action of a fluid.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image.
