One interesting note is that we left the highbanker stored upright over the winter. The little gulch almost goes dry later in the season. The creek is very small and so had to be ponded up for the system to work, and it used nearly all the water in the creek while operating. In this case we used a Keene 175-30 highbanker / dredge combo for the test work. It was mined out by hand as the stacked rocks reveal but some gold still remains. It is a small short drainage but was very rich at one time. This photo was taken on Skookum Gulch in the Wrangell Mountains of Alaska. Any claims not passing the exam would be lost. Short story is samples had to be taken at various locations to prove the claims have paying quantities of gold. I was involved in some validity exam testing on some mining claims in Alaska a few years ago.
