As part of our visit to Hawai’i Volcanoes National Park on the Big Island we took a 1.4 mile round trip trail across a cooled lava flow. The trail was rugged and rocky but led us to the Pu’u Loa Petroglyphs. There are some 23,000 images and are said to be . . . “dated geologically between AD 1200-1450.” (NPS)
It was a great experience to hike over a lava field and search for cool looking petroglyphs (our favorite being the Honu!).
