Potholes and Other Bedrock Traps
Potholes in bedrock can trap placer minerals and even be glory holes. They are, at least, interesting geologic phenomena, and at best, a treasure trove of gold nuggets.
Undiscovered Placer Deposits in Alaska
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
