Found the benchmark under about 4 inches of dirt. Dug it out the best I could.

Snapped a few photos. Did not find what Oragne Dawg left behind. Well it has been 7 years.

Benchmark in good condition.

I need to check the validity of my GPS, i had to kick around for this one. GrizzFlyer's picture was right on the money. I left something for the next finder.

Station recovered as described in good condition.
