Hiking to Harney Peak feels a bit like being the hero of a fantasy story. The towering spires of the black hills already have a magical quality. Add to that dirt that shimmers in the sun because it's speckled with mica, a castle-like structure at the top of climb, and chipmunks that will practically climb into your lap in hopes of a scrap of granola, and you have the makings of an epic adventure tale.
