After finding the nearby cache, we couldn't leave without hunting for this cap, too. We knew there had been some recent DNFs, but we were hopeful. There didn't seem to be a divot or any other sign of a cap around GZ, but Mr Shark, who was excelling in every way today, scuffed a spot lightly then went off to get his phone with the metal detector app. In his absence, Mrs Shark probed that spot and hit metal on the first try. She shoveled an inch or two of dirt away to find a plain flat piece of metal that appeared to have a straight edge. One more scoop just as Mr Shark returned revealed another edge--curved with a few stamped in letters. Brass! (The first metal piece is a collar surrounding the cap.) When we were done, we blended our diggings back into the landscape and left the cap exposed for whoever gets there before it fills in again. Thanks a lot to those who post very helpful context photos and those who maintain the pages that make those logs and photos so accessible. Thanks, outforthehunt, for another well chosen cap in a pleasant location.
