Humphries Peak

Looking across a Sunset Crater lava flow towards the west shows the collapse structure of Humphries Peak - the largest mountain in Arizona. Humphries Peak used to be considerably taller before it suffered a lateral collapse much like Mount St. Helens did in 1980. The whole region to the northeast of the mountain is covered in debris from the event.

I'll be on vacation for a week, Wednesday to Wednesday and I'm not sure how often I'll be able to post pictures, but if I get a chance, you can be sure I will. I'll save my destination as a surprise.
