How are courses measured?

Courses are measured as the crow flies, in a direct line from control to control. Unless you have wings, you will travel farther than this distance! Courses are measured in kilometers, so a good rule of thumb is to simply round up to miles to estimate how far you will go. So in a 5 kilometer race, you’ll likely travel up to 5 miles.


Lincoln  Tree Farm is a working tree farm that has had a harvest in the last month.  As a result, the southeastern corner or the park will be out of bounds as Mother Nature recovers from the activity.

The Championships will be technically very challenging at all levels.  JV and Varsity will depend on bearing and pace count to find their controls from appropriate attack points.  Trails are mostly wide and fast.  2 meter contour lines on a 1:10,000 map will help you plan appropriate routes in and around the gentle elevations of the park.  Expect a wet day with a high in the mid-high 40’s.


There will be a shuttle between parking and the start/finish.

**Please check back closer to the event date for details on the shuttle schedule**

Why is there a start window?

This event uses an interval start, which means that participants are started in waves instead of all at once. When you arrive at the start tent, find the chute for your course and follow the start volunteer’s instructions.

Those participating in School League (WIOL) will be provided a specific start time, and should show up at the tent several minutes before their designated time.

Registration for the School League is done through paper forms. For more information, visit the School League (WIOL) page.

What’s an e-punch?

An e-punch records your race. At each control, you’ll dip the e-punch into an electronic box, which will beep and flash as confirmation. After you finish, you’ll download the e-punch at the download tent and get a receipt that show which controls you visited and how long you took between each; these are your “splits.”

Part of the fun of orienteering is comparing your splits with people who completed the same course, and discussing the routes you took!


Online pre-registration closes: 9pm, Thursday, February 16

Day-of-event registration is available by cash or check, made payable to Cascade Orienteering Club

Registration for School League (WIOL) is done via paper forms. See the School League page for more information.

Lincoln Tree Farm is best known for its whack-a-mole brush piles. Swaths of logged areas, mapped as light-yellow-tan “rough open area” on the map, are speckled with green dots representing tall brush piles. A major dirt road and power lines run through the center of it all, providing a confident feature to re-orient oneself on. There are some delightful open forest areas of the map, where there is little underbrush, that may cause bouts of gleeful skipping. This is balanced out by the areas of low-lying blackberries on the map, that cause tripping.

Lincoln Tree Farm is also a bit unique due to its 2-meter contours, instead of the traditional 5-meters. There are also areas that use form-lines, which are dashed contour lines that appear between the regular contour lines, thus providing areas with contour information for every 1-meter of elevation! Advanced course participants will be challenged when navigating these subtle contours in the forest.

Navigational Challenge: 7/10

Physical Challenge: 4/10


Return to the Finish
All participants MUST return to the finish and download their e-punch or turn in their punch card.

Even if you have not finished your course, you must still return to the the finish and confirm with event staff that you have returned safely.

Out of Bounds
Some areas may be marked out of bounds. It is imperative to respect these boundaries to maintain our relationships with land managers. Participants MUST NOT go out of bounds. Any participant caught going out of bounds will be disqualified.

Course Closure
All participants MUST return to the finish by course closure time. If a participant does not return by course closure, event volunteers will begin coordinating a search party.

If you need a long time on the course, start as early in the start window as possible, wear a watch, and be prepared to cut your course short to make it back by the course closure time.

All participants MUST carry a whistle on the course. Complimentary whistles are available at the start tent (please only take one).

If you are injured on the course and need assistance, blow three long blasts to call for help.

If you hear a call for help, abandon your course to find the person in distress.

Part of the fun and fairness of orienteering is navigating your own course, so please be polite when you find a checkpoint and don’t holler that you’ve found it.
