What is a Rockhounding Field Trip?

Rockhounding is the recreational collecting of rocks, minerals, fossils and gemstones

in their natural environment. Rockhounding field trips make this possible. While on the field trips prospecting we learn about geology, minerology, and identification of stones.

Where do we collect rocks and minerals?

The Pacific Northwest has a wide variety of rocks, minerals, fossils and gemstones. We explore and prospect many interesting places such as rivers, streams, valleys, mountains, beaches, roadcuts, desserts and forests. We also occasionally visit museums and rock shops.

What do we collect?

Below is a sampling of materials that have been collected on club field trips.

We have collected many “varieties” of all the following materials.





Oregon Fire Opal

Petrified Wood
