If you are thinking about going north to Alaska to go gold prospecting this is the blog post for you: Significant Metalliferous Lode Deposits and Placer Districts of Alaska by the US Geological Survey. This is pretty much the bible of Alaska gold prospecting.
It has 110 pages of information about the various sites and productions. It’s a little dense, but it should read like John Grisham to anyone interested in gold prospecting in Alaska.
