Talks & Demonstrations

We will be updating our events for 2018, but in the meantime, you can read about the past events. Our newest demonstration, The Ultra Violet Light Tent, was such a success that we’re going to make the tent bigger and bring in more glow-in-the-dark rocks.


Saturday, January 14th

11:00 a.m.

Marla Miller, a geological sciences facility member at the University of Oregon since 1997 is a geologist, photographer and author of the new second edition of Roadside Geology of Oregon. Her work showcases the states spender while also helping enthusiasts understand geologic processes at work. She will be available to sign her book at the Agate Festival.

12:00 noon to 1:00 p.m., 15 minute intervals. 

See and hear the unique story of the “church of the agate windows.” Yachats Presbyterian Church, 7th Street, behind the Commons.

Beach Booty 101. Ranger Cameron (also known as Ranger Clameron, because of his knowledge of clam digging in this area) has been an enthusiast of beach rock-hounding for more than 12 years. He is an Oregon Park Ranger who has given many talks for kids of all ages on stuff you can find on the beach — agates and much more.

Sunday, January 15th

11:00 a.m.

Chris Landau is a geologist trained in South Africa, and has linked dowsing to geology for many years. He has used geology and dowsing to find water wells, as well as creating geological maps, geomagnetic maps and aerial photographs. He understands how and why the dowsing rod works for almost everyone. He moved to Florence in 2015, and offers dowsing classes in places such as Cook’s Chasm and Thor’s Well.

1:00 p.m.

Guy DiTorrice is well known locally as “The Oregon Fossil Guy”. Passionate about the treasures that can be found literally under our feet, he conducts fossil finding tours along the central Oregon coast. He’s an engaging speaker who appeals to audiences of all ages.

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


George Mazeika : Wire Wrapping

Saturday: 12:30 – 1:30 / Sunday: 12:00 – 1:00

George Mazeika of CoastBear Enterprises LLC, will be on hand to demonstrate wire wrapping of stones and the Viking weave. Wire wrapping is commonly used for less valuable stones, and it is a very popular jewelry-making technique whose basics are easy for the hobbyist to learn.

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.

The Ultra Violet Light Tent

For the first time there will be a special display of fluorescent minerals, whose vibrant colors are only visible under ultra violet light.


Agate Sandbox

Bring the kids (12 and under) to the sandbox where they can search for agates and take three of their favorites home with them.

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.

The Oregon Fossil Guy

Guy DiTorrice will be here to talk with you about finding ancient treasures along the central Oregon coast
