Willamette Mission Park is a 1,680-acre state park with many miles of running trails winding along the Willamette River, backwater sloughs, and agricultural fields. The park is very accessible, yet large enough to give participants a feeling of "getting out there." There is a nice mix of paved paths, open farm fields, and wooded "thickets" to explore. The terrain is flat and looks open, but most of the orienteering route choices will include trails due to blackberry thickets or other dense vegetation or cultivated land which may or may not be planted. The advanced course will be designed with the challenge of multiple route choices for most legs, and will be a little longer than typical due to the flat terrain.

Orienteering map from previous event
All CROC orienteering events are put on by volunteers, and the meet director can almost always used some extra hands. Please keep in mind:
- No prior experience is needed for many of the tasks
- You can help out AND still run your course of choice
- Your entry fee is FREE if you help out with a meet!
Typical ways to assist are: helping with starts and finishes, checking in folks at registration, and picking up control flags after the course closes.
Please contact the meet director at the email address on the bottom of this page if you'd like to volunteer at this event. For more details, see the Volunteer pages.
Results are posted to the Events & Results web page a few days after the event.
