Reclamation reality check

The artist’s rendering of the post-reclamation Rosemont Copper Mine shows a striking difference in landforms between the graded mine-waste pile and the surrounding undisturbed terrain (HCN, 11/22/10). Particularly noticeable is the difference in what geomorphologists call drainage density, or the total length of drainage channels per acre. The unvarying slopes and rock rundowns in the […]

Chinook, Magnum and American Fuggle — these are just some of the Pacific Northwest’s many organic hop varieties.
