Returned from a 10 mile hike along rugged terrain. 60 lb pack and wading across islands. I explored the island just east of Herzog island in Carderock MD. A massive island with only small signs of human activity. I found large bones, snakes, turkey and plenty of spiders. No gold though :/. I was using a metal detector to search along the quartz veins on the island. I also did a decent amount of quartz crushing along some of the larger quartz veins. The detector showed no sign of metallic substance in the veins. I did this process for about 2 miles, searching all of the quartz with my eyes and the detector. I did find one quartz area with some silver alloy sheet. Much the same look as the one I found the day previous, In a location 2 miles east, at Carderock.
