The Big Island is full of lava fields. Juxtaposed with the fancy resorts and their lush tropical flowers, the lava looks rustic and unfinished. It’s like seeing a huge construction site sprawling out beside a perfect model home.

Along the Mamalahoa Trail, the lava revealed ancient petroglyphs and carvings.

We walked on the King’s Highway, just a few feet from a golf course, and the petroglyphs carried us back in time.

It was here, among the petroglyphs, that we saw a girl and a boy hurrying over the lava rocks.

“Mother and father will be worried about us,” the girl said to her brother. “But we had to get the crystal from the volcano.”
