Kind of strange saying this about dirt, but the Oak Creek Orange is absolutely beautiful! I used it for dirt trails and farm ponds on my HO scale layout of western Oklahoma and eastern New Mexico. It has a nice warm glow that compliments the rugged terrain and red rocks. Also looks great as a MOW access road next to the Cumbres and Toltec ballast.
This item might work well for an O Scale road. I bought two bags and after sifting it down for N Scale I didn’t have enough to do a driveway. It was far too course for the smaller scales.
