Another small boulder field along the South Branch of the Patapsco River. Six problems are currently established at Erebor, there's potential for a few more but require heavy cleaning. I didn't find an historical name for this area, so, considering the names of the other established problems, I'm calling it Erebor.Routes (L->R, Top->Bottom): Brunson Bunker, The Arkenstone, Smaug, Elevenses, Pippin, and Merry
