Rock Seeker was founded by Don Gerig, a passionate geology enthusiast seeking to share his knowledge and appreciation for the world of rockhounding. After years of collecting quartz, agates, and other mineral specimens around his Pacific Northwest home with his daughter, Don was inspired to create an educational platform for fellow hobbyists.

Today, Rock Seeker provides expert tips on identifying rocks, minerals, and fossils as well as recommended destinations for finding these specimens across the United States. With a lifelong passion for geology and decades of rockhounding experience, Don created this site as a resource for both novice and seasoned rockhounds.

At Rock Seeker, readers can enrich their knowledge of geology and rock identification through informative articles and guides. The site offers insights into local geology, determining the origins and properties of different mineral and fossil types, and building an impressive mineral collection.
