Title: Trees Buried in Volcanic Sediment, Sandy River 1
Trunks of forest trees, initially growing on a terrace above the Sandy River (Oregon) at Oxbow Regional Park, were buried by rapid deposition of sediment following a dome-building eruption at Mount Hood in 1781. Erosion during a flood about a week before the photo was taken exposed this "ghost forest".
In the photo is Dan Daly, a naturalist interpreter with Metro Parks. The rope was part of a barrier at the top of the bluff to keep park visitors back from the unstable bluff edge, but the whole rope fence slid down and got tangled in the tree trunks below when the bank collapsed.
