Southern Oregon has plenty of opportunities for recreational rock and mineral collecting. The ledges, river and lake gravels produce a wide variety of minerals including gem-quality specimens. Due to most of the sites mentioned below are located along the river and creek banks, the best rockhounding time is during the summer and early fall months when the water level is low and more materials are exposed. Before accessing the collecting area, contact pertinent agencies the most up-to-date information and regulations.
North Fork and South Fork of the Umpqua River
Minerals may be found on the river gravel beds along the banks of the North and South Forks of the Umpqua River. There are small pullouts at North Fork Umpqua River along Highway OR 138 from the town of Glide, but a river access can be steep and slippery.
For the South Fork of the Umpqua River, take Tiller Trail Highway, running east of Canyonville. Find pullouts with the riverbank access. Check the river gravel beds near I-5 under the bridge in the town of Myrtle Creek.

The Oregon Rockhounding Map provides information about some of the many rockhounding sites of the state of Oregon. Information is subject to change at any time, and Oregon Discovery team cannot guarantee that is either current or correct. Be aware that there are some mine claims and private lands near the public collecting areas. Determining the land status and minerals' collection rules at the site is your primary responsibility.
Currently, this map is incomplete but new rockhounding sites and related details will be added in the future.
