D is for Devastation Trail: Volcano National Park, Hawaii

Pu'u Pua'i created after the 1959 eruption of Kilauea Iki.

A late afternoon stroll along the Devastation Trail was a stark reminder of both the power and the impact of an eruption.
It's 57 years after Kilauea Iki erupted and the is landscape is still barren with only a hint of recovery.

Reamrkable devastation after Kilauea Iki eruption.

PS - a D at last on my travels....
