Beach Combing 101 with Agates of the Oregon Coast by K. Myers, who has served as the Yachats Agate Festival’s “Rock Doc” for a number of years. Myers is the author of Agates of the Oregon Coast, a handy guide to finding agates, jaspers and other natural treasures on the Oregon Coast.

1:30 p.m.

Cameron Rauenhorst (also known as Captain Clameron because of his knowledge of clam digging in this area) has been an enthusiast of beach rock-hounding for nearly 15 years. He has worked as Oregon Park Ranger who has given many talks for kids of all ages on treasures you can find on the beach – agates and much more.

 Talks are given in the Civic Meeting Room, just inside the east entrance.

Agate Window Tour:

Saturday, January 18: 12:30 p.m.

The Yachats Community Presbyterian Church, also known as the Church of the Agate Windows, will offer a brief talk about the story behind the amazing six large panels of agates located in the sanctuary of the church. The church is located on 7th Street just to the west of the Yachats Commons.


During the weekend a variety of demonstrations will take place in Room 7 of the Commons. These will include the art of making cabochons and the age-old art of flintknapping.

George Mazeika : Wire Wrapping

George Mazeika of Coast Range Designs will be on hand to demonstrate cabochon making and the wire weave. Wire wrapping is a very popular jewelry-making technique whose basics are easy for beginners to use.

Cabochon Making: Saturday 12:00

Wire Wrapping: Sunday 12:00

John Piri: Flintknapping

Flintknapping is the process of chipping away material from high silica stones like “flint” in a carefully controlled manner with special tools to produce sharp projectile points or tools. Only the purest silica-based stones will provide fracture predictability required to achieve the finest works. John Piri will be demonstrating his technique all day Saturday and Sunday.

The Mohs Hardness Scale

The Agate Festival also featured a demonstration of the Mohs hardness scale, inviting visitors to experience the varying hardnesses of different types of rock via the “scratch test.”

The Mohs scale provides a quantitative way for geologists and rockhounds to identify the hardness of minerals in the field. It ranges from a value of 1 (the softest), for talc, to 10 (the hardest), for diamond. The scale is named after a German geologist/mineralogist, Friedrich Mohs, who introduced it in 1812. The scale is based on the ability of one natural sample of mineral to visibly scratch another mineral.


Rock Doc

Got a rock you can’t identify or are curious about? The Rock Doc will be available to answer your questions about your mystery rock.
