RHH's photos with the keyword: obsidian flow

These will be the last photos I post of our Oregon-California trip. They are of the last place we visited before heading home, the obsidian flow at Newberry Volcanic Monument in Oregon. This flow is relatively recent, only about 1300 years ago and is spectacular with obsidian everywhere including massive blocks. It was tempting to pocket a few pieces but there are draconian fines for doing so and getting caught. For those who do not know, obsidian is black (usually) volcanic glass, some of which is more visible in the inset photos than that on the slope in the right of this photo. There are trails through the flow and it was one of favorite places at Newberry.

This is a boulder made almost entirely of obsidian and photographed at the obsidian flow in Newberry National Volcanic Monument in Oregon. What looks a bit like coal glinting in the light is actually the volcanic glass, obsidian.

This is a close-up of an obsidian boulder at Newberry National Volcanic Monument in Oregon. It is in an area covered with obsidian formed by a flow that is estimated to have taken place about 1300 years ago.

There was still snow at these elevations when we visited the obsidian flow in Newberry National Volcanic Monument in Oregon. These are pieces of the black volcanic glass known as obsidian, acres of which cover the ground in this area.
