I found an old abandoned trail on my off-trail wanderings in Hawaiʻi Volcanoes NP.
Hopefully, in the next few weeks, I will find more information about it, such as its age and where it used to go. Even my old historic map from 1984 does not have the trail on it.
Iʻm heading back in a few days and will try to walk it as far as I can; maybe I will find more clues.
Itʻs cool. The ahu( cairns) are still there, but a huge 15-foot-wide crack on the fault line prevented me from going any further on the north side of the fault.
