While walking up to the Donner Train Tunnels from where we parked we were perplexed as to why there were perfectly manicured rock trails seemingly where there should not be any. We started poking around and realized we had walked right past some pretty epic petroglyphs. I say pretty epic because there aren’t a whole lot of them around this area. Apparently the area was knows as a region where various groups of American Indian groups would gather and trade. The petroglyphs were thought to have noted the meeting spots with meaningful images.
