Opal Butte

Morrow County, Oregon, USA

Opal Butte is a mountain in Oregon famed for producing specimens of Opal – hence the name!

The site produces a range of opal including common, precious and Opal-AN (hyalite).

The best source of information on this locale is the 1988 article by Kevin Lane Smith, linked below from the GIA website.

I have not been able to find much more up to date information – including whether or not the West Coast Mining company is still operating.
