Dirty Diamond Diggers, Fort Plain
An excavator-assisted private dig on the western edge of the Herkimer belt, where the operator opens fresh rock for you instead of leaving you to sort picked-over spoil. It is sold as a booked private session for one or two people, and the trade-off for the price is that nothing you find is weighed or limited. Tools are supplied, or bring your own.
