A delightful read full of character, this review of Colorado precious metal mining accomplishes its task well. The rush and excitement, rise and fall, boom and bust in mines, towns, and hearts of those who participated in these events is well covered, and it is a particular joy to hear so much of it conveyed in their very own words (from newspapers, diaries, letters, etc.). This is indulged in to such a degree that it may be off-putting to some, but I find it to be a characteristic strength of the book. The main weakness of the book is the emphasis on silver and gold at the expense of other metals that would have better framed the challenges and opportunities of the industry, and thus better encapsulated hte history. The book also struggles slightly (due to its size vs its scope) in keeping up with the booming developments in hard rock mining in a broader contextual sense, but the review of the changes that better smelting brought to the industry does scratch this itch somewhat. Overall though, for the size of the book given its scope it does creates an admirable and accessible portrayal of Colorado precious metal mining that certainly is worth the read.
