I've been using MIG pigments/pastel chalk on models for quite awhile and it struck me that these would work well with Epic terrain.  Because of the nature of pigments/pastel chalk, you can quickly get a good result that would take much longer to achieve using regular paint.
For this low hill I used foamcard sections covered with PVA and dusted with beach sand.  Once dry, the whole bit was given a coat of gray Krylon primer followed by a coat of Minwax Dark Walnut wood stain.  The "crater" was just an extra blob of GS that was left from another project.
After some selective highlighting in grey around the hill, I used a hobby knife to shave some dust off Nupastel sepia, grey, and rust color pastel chalks.  The chalk dust was then applied in spots with a largish brush(W&N #6 round) around the hill and on the flat spots.  All of the chalk was fixed with turpentine and then the hill was given a coat of Krylon matte.  Start to finish it  took about 45 minutes in 90+ F heat.
The great thing about pigments/pastel chalk (Yes, they are really the same thing! *ducks*) is that the fixer does all the blending for you and evens out any goofy spots.  You can be pretty sloppy and get away with it.
