Hello and welcome to Open Adit West! We are a family-run mineral specimen business. My name is Mark Kielbaso and thanks to my father, Joe Kielbaso, who has been collecting since he was a kid. He has passed his desire and passion for field-collecting and acquiring great mineral specimens to me and my sister, Lisa Brower. Please read more of our mineral past on our. Page and see some great photos from our field collecting adventures at the Elmwood Mine, Tennessee, Brushy Creek Mine, Missouri and Cave-in-Rock, Illinois..
