’Lava field at the Mc. Kenzie Pass.’

	Vegetation struggles to survive on the 3000 year old lava field at the Mc. Kenzie Pass in the Cascades Mountain Range. On the horizon are the snowcapped volcanoes known as The Sisters which were responsible for the lava outflow. The lava in this area is called block lava. The jagged blocks were formed as the lava cooled rapidly on the surface of the flow while molten lava beneath continued to flow. Like ice breaking up on a river, the blocks were broken and jumbled.
