Beginner's Guide to Alluvial Fans and Deltas on
Landsat GeoCover Satellite Images
Alluvial Fans and Deltas are generally easy to recognize by their triangular shape. Alluvial fans are often a purple, magenta or pink color because of the exposed soil on their surface. Deltas generally are covered with vegetation and show characteristics similar to marshes. Both deltas and alluvial fans can show distributary channels branching from a main stream at their head.
