Good luck out there erinleigh with the metal detecting. I have created a facebook page in hopes to get other Montana metal detectorist together to share finds and information. If you do the facebook thing just like the page and let other metal detecting friends know about it as there is hardly any info on metal detecting here in MT so hope this site can help people.
