This interpretive site is situated the Newberry National Volcanic Monument. The landscape was formed by various lava flows and includes many tree molds that were created as the lava burned through the wood and cooled into casts.
The former Lava Cast Forest Geological Area (now part of the Newberry National Volcanic Monument) was established by the Forest Service in 1942. The geological area was established to protect the many lava trees and tree molds which occur in this area. The various flows of the Lava Cast Forest were all erupted from the Northwest Rift Zone of Newberry Volcano. This site offers a one mile paved self guided interpretive trail with barrier free access. The trail loops through an area where hot molten lava erupted from the northwest flank of Newberry Volcano and engulfed the forest 7,000 years ago. The landscape now includes the "casts" or molds of these ancient trees. Colonizing plants such as delicate penstemon flowers and Indian paintbrush, have now taken root in the rocky soil. Ponderosa pine trees have re-established themselves and flourished as well. The landscape now includes a blend of the past and the present.
