Re: Re: Re: Roy Johnson's Rock in the Photo Gallery

Thanks for your reply Montana. I think you are right that it is obsidian. It came from a pile of landscaping
cobbles on the East Mesa in Albuquerque, NM. A few miles west of the Rio Grande are four or five
dormant volcanoes that could be the source of the obsidian. I've found a second stone in the same
place that resembles the first except that it has streaks of white agate running through it. I've slabbed it
and will proceed to shape and polish it. The first stone was fractured and fell apart in the shaping stage.
