I’ve seen many rock cairns near the start of the dirt road that goes from Chitina to McCarty, Alaska. This road follows an old railroad bed and is 60 miles to MCCarthy and across the river is Kennicot, an old cooper mine town now owned by the National Park Service. This road is one of the few roads into Wrangell-St.Elias National Park. The rock cairns are right outside of Chitina which is a small Native American village. The road is very rugged and take a spare tire or two since this was a railroad bed with nails because you will need it for your flats.
