Impression of Dugway

Using the power fractal to drive the noise simply gave more interesting variations to the pattern.
Using a get position produced a very uniform look. I still have the file open, here is the texture get position gives when substituted in this set up.

Just for curiosity's sake have you tried to combine the voronoi with the get
position and the PF after the voronoi node also?
This is an interesting way of using the built in get position of the PF to
combine a PF with a function.

Cool. More please!

I tried a good many configurations. It seems like using a PF after the voronoi noise could indeed give a similar look, or maybe even the same exact thing, but I haven't found that set up and settled on this after a lot of experiments that weren't all that great. This method grew out of recently trying to get agate like patterns.   

I'm posting the TGD and (hopefully) the TER file (it is large) I created in file sharing. (it takes and hour to generate the starting heightfield and erosion without the TER file)

You can get some agate like patterns with a very warped PF.

Thanks Ulco,
Your method gives nice naturalistic patterns.
