Salt Pans and Alluvial Fans

We're close to the middle of Death Valley, at Badwater Basin, with access to salt deposits which spread for miles.  Everything in the bottom third of the image is salt.  It is the lowest area of the valley--282 feet (86 meters) below sea level.  The image also several alluvial fans--triangular-shaped deposits of geological material (from clay or sand to small rocks) carried by water descending from canyons or faults in the mountains behind.  There are four or five of them in the image. They are small--in fact far smaller than the very extended ones at the base of the higher mountains on the other side of the basin, which slopes gradually downwards. We had been passing them virtually continually  on both sides of our bus since descending into Death Valley, pointed out by our expert guide; he has provided superb analyses of the geology we have encountered and how it has evolved over more millennia than we can grasp.
