Volcanic formations (3/10)

List item

Much of eastern Oregon is made up of volcanic rock and soil. That makes volcanic formations like this one fairly common. The scrub and grasses that are growing here are quite healthy, despite the lack of moisture, because the soil is so fertile.

The formations in the background are carved out of volcanic rock by a combination of rain and wind. The wind is normal and frequent, and when it does rain, it can be a hard rain. Over many centuries, this is the result.
