Part of the Ultimate Orienteer Series, our variety pack of orienteering events.

Day 1 of a 2-day event at Fishtrap Lake. We’re going old-school! While each day will count separately for Ultimate Orienteer standings, we’ll also add the two days together for 2-day results.

Make it an orienteering weekend and stay for Sunday’s event, also at Fishtrap.

Out of Bounds areas

Most of the area we’re using belongs to the Bureau of Land Management. They have identified several sensitive areas which are out of bounds for our competition. These areas are clearly marked on the map with vertical purple lines. The courses have been designed to avoid them, so make sure your route choice does not include travel through ANY out of bounds areas!


We may have water on the course, but you should plan to take your own. Even though we’re starting early, Fishtrap in June can get hot, so be prepared!

Mountain Biking

Mountain biking is only allowed for control pickup, so if you want to ride your bike, please volunteer to pick up controls after the event is over.


Per our permit agreement with the BLM, your dog is not allowed to accompany you on the course. Please respect this restriction.


Camping areas near Fishtrap:


We’ll have 4 courses each day. Course distances will be provided once the courses are finalized.

Short Advanced – Ultimate Jr (20 and under) and Masters (50+)
Long Advanced – Ultimate Open

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.


Check back later for special notes from the Course Designer(s).


Registration: 10:30am-12:30pm
Starts: 11:00am-1:00pm
Course closure: 3:00pm*

Newcomer instruction: 11:00am-12:00pm

*If you think you might take a long time on the course, start early in the start window. Also, wear a watch to ensure that you return to the finish by course closure time, even if you have to abandon your course to do so. Those returning after course closure will be disqualified and will make the volunteer staff very grumpy.

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.


Note: because we must pay an additional permit fee of $5/person/day at Fishtrap, registration fees have been raised by $5 (or 2 points if you pay with volunteer points) for this location.

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: Thursday, May 10 at 9pm

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

Featuring unique scabland terrain, Fishtrap Lake is challenging, yet accessible, and a complete joy to navigate. On one hand, there are tons of tiny cliffs and rock details. On the other hand, there are so few trees here, that the views are expansive, allowing you to orient yourself off of faraway cliffs. Fishtrap also provides a perfect opportunity to test compass skills, since there is little to stop you from beelining straight to the next control.

Navigational Challenge: 7/10

Physical Challenge: 7/10


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.
