The copper deposits of Prince William Sound attracted the attention of prospectors as early as 1897, when the properties of the Alaska Commercial Co. on Landlocked Bay, the Gladhaugh mine at Ellamar, and the Big Bonanza mine on Latouche Island were staked. Doubtless many deposits of copper minerals were known to the natives and perhaps to a few traders long before that time, yet little if any effort was made to investigate them. Interest in copper grew rapidly after 1897, but not until 10 years later did it reach its high point. By 1907 the number of men engaged in mining copper and in the search for cbpper in this region had increased many times, and the amount of money invested in such enterprises had reached large proportions. Furthermore the possibilities of the Sound region for producing copper had been presented to investors in many places outside of Alaska, so that the interest in it was by no means local. After 1907, however, the less favorable financial situation, the failure of most of the prospects to become mines, and. finally the World War made the raising of money for developing copper properties difficult and reduced prospecting almost to the vanishing point. The only place where copper is now being produced on Prince William Sound is at the mines of the Kennecott Copper Corporation on Latouche Island. The copper deposits of the Sound have been studied by many persons representing either the Federal Government or private investors, and a considerable literature on the subject has accumulated. This was summarized by Johnson 1 in a report published in 1915. Several papers dealing with the geology and copper resources of Prince William Sound or of particular districts in it have appeared since that time, notably papers by Johnson 2 and Bateman.3
