In the past David Lavender has written books in varying categories -- non-fiction, and fiction at the adult level, and juveniles -- and most of them have dealt competently with our pioneer west. This most recent contribution is a colorful, fictionalized social document set in Colorado in the early 1880's. Freed from a charge of murder, Johnny Ogden attempts to re-establish himself in the community by building a road to Red Mountain which will open up mineral resources in the area. The fate of Johnny and his enterprise make up the heart of the book. A little overlong, perhaps, Red Mountain is nevertheless an authentic and well researched addition to the groaning shelves of its genre.
