Each year, Mojave Underground produces a calendar of abandoned mine locations throughout the United States and the world. Photographs are submitted by photographers who explore abandoned mines and a dozen are selected to be featured in the calendar each year. For the last few years, Burgex has sponsored these calendars and makes them available for purchase at cost. One calendar available for $10 and two for $15. Shipping is $8 flat with USPS regardless of the amount of calendars purchased. Buy using the link below:
