Sheldon NWR closed non maintained roads due to extreme fire danger. Opal mining at the Peacock Fee dig is still open (That access road is not on the open road map.) Details of the other closures in Oregon can be found at http://www.scofmp.org/lifc.shtml. Swordfish Mining claim sales and tours are suspended until the imminent danger has passed. Thanks for your consideration.
Just a short note with a link to a page on mining a specimen. http://www.ukminingventures.com/weardalegiant.htm
