Re: Mystery channels
Check out the Wide Angle Picture
Notice these channels start on the large crescent dune and not the smaller one (This dune is the size of a mountain.
I have noticed recently that channels are present where subsurface reserves of liquid would be unlikely without a replenishing source (such as rain. The HREF="http://www.edwardsaquifer.net/geology.html">Edwards aquifer
in central Texas needs to be replenished by rain because it is not very large). Does that mean whatever is making the channels was deposited from the air before it liquefied?
