What interested me was it looked like something flowed from
south east to northwest in a fan like shape
a lot you see in pictures on mars.
Lava, under the sand/sediment ?

I have seen in washes out by usery mountain
(Usery Laws ???) AZ has none as far as I know.
here in East Mesa AZ Exposed Lava flows that look like
you see near Grants New Mexico.

I think under that stuff you mention
are features hard to see but still visible
in a broad general sense of the term.

and, there is a crater looking thing right where the EQ happened.
Possibly a Brecca Pipe or Meteor crater ?

No one sees these but me , I guess.

geoff

Gey Geoff,
                in what way strange ?  it appears to be quite a large wash 
area where
  many sediment laden streams flow out of the surrounding hills.  Those 
sediment
deposits are then being cut and recut by ongoing water flows during the wet
seasons.
   Its been ~11 years since my last visit to that region.  An interesting 
place to do
geology !!

cheers
