(Hawaii)
Lava Tree State Monument is a public park located 2.7 miles (4.3 km) southeast of Pāhoa in the Puna District on the island of Hawaii. It preserves lava molds of the tree trunks that were formed when a lava flow swept through a forested area in 1790. (Ref: https://en.wikipedia.org/wiki/Lava_Tree_State_Monument)
