I just visited your web site and viewed the location of the Avenger Mine.  I know exactly where it is located.  It is privately owned and a house is built up on the hill in the same area.

Heading west on Highway 24, BTW, that is US Highway 24, not Interstate 24, you pass the western exit to Green Mountain Falls.  Continuing west, you will pass several houses on the right side of the highway and start a gentle climb towards Crystola.  The driveway to this location is just east of the Pines something or other RV park, campground, car dealer on the right side of the road.  The separated sections of the highway will just start to come together near this driveway.
