More views of the Roughs. I posted a picture earlier this year a few miles north from this area.
This unique area is where large blocks of sandstone have been offset from the rest of the earth through tectonic processes. A large fault called the Eaton Roughs Fault Zone runs between the Mad River and the Van Duzen. There is a good description of the area for all you geology nerds here. The processes have created these strips of sandstone where apparently some layers have more developed soils than others. Most of the areas are barren, and have sporadic communities of manzanita and whitethorn. Then there are the junipers? over a understory of various manzanita species. Lastly, where layers have better developed soils, there are strips of Douglas-fir forests. This has to be one of the most interesting landscapes in Humboldt County.
