It was not that difficult, but it's easy to say if you always have to wait hours
even for a partial render.

I know, several nights starting a render in the evening and recognizing some
mistakes in the morning... It's quite a new way to work when dealing with such a
slow matter.

That's about what it's meant to be, i don't have a real object i derived this
from, it's just from imagination, memory and the caprices of randomness :-)

Thanks, that about sums it up: the more detail, the more time it takes, the only
nice thing is that it does not need much memory.

I think you are right about the type of stone, granite would probably need some
additional sharp medium scale structure, but i think there are quite a lot of
sandstone formations like this.

absolutely great! Think i have to try out to work with isosurfaces. Unfortunately,
Moray dosen`t support Megapov at this moment .-(. So i have to change  code by hand.

I've been planning on doing something like this, maybe I'll not bother, this
is amazing.

Having just returned from a vacation to the southwestern United States, I
can definitively state that the real thing is far more impressive.  The only
major problem with this picture is that the striping on the cliffs is too
regular.

As for the rocks, the rock formations in the southwest are formed almost
exclusively from sandstone and other sedimentary rocks.  Granite is usually
found only in the bottommost layers of the formations.

Sure it is, especially at this tiny size. Who am I to compete with reality ...

Now that you say it... 
Although IMO the straight stripes themselves are quite right, but they should be
interrupted by some other structures.

I think the ground level could look a little more grainy or sandy...  Light
traces of water and wet ground will appeal to tae eye as well... Looks great
almost picture perfect... =)

Thanks, 
including isosurface support in moray would be quite difficult because you have
to display them somehow.
