Notice: Because of permitting problems, we are moving this year’s Marmot O’ Cup from Fisk State Park to Fishtrap Lake. We have submitted a permit for Fisk for next June. Since we received notification from the park about our permit in late May, there was no time to design the courses required for a National Ranking Event. We’ll have 5 courses each day but neither day will be a sanctioned NRE.

Join us in celebrating the final two events of this year’s Ultimate Orienteer Series!

This year we’ll be finishing the season with two exciting events at Fishtrap Lake near Spokane. In addition, Saturday’s races will comprise the Pig War Challenge, a semi-annual competition between British Columbia and Washington. Come out and Defend the Pig!


Fishtrap Lake (driving info coming soon).


Experience the unique scabland terrain of Fishtrap Lake, where the vistas are expansive but details are plentiful. There are few trails in this area, so you’ll  appreciate the plethora of contour and rock details as you traverse this beautiful desert area. June is a great time of year for wildflowers here, so you might want to take a moment to enjoy them.

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!

A portion of the venue is owned by local rancher Rex Harder, who has generously allowed us to use his land for several years. Please patronize his friends who own businesses in Sprague if possible.

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.

COC members – register using volunteer points

COC members may use volunteer points (5/day) to pay for a portion of their entry fee (online pre-registration, Fishtrap Lake only). Email and ask for a discount code, specifying one event day or both.


All our events operate on volunteer power. If you’d like to help out at Fishtrap Lake (either or both days), check out what’s available and sign up here.

Timing system

We will use the SPORTident electronic timing and punching system for all events. All competitors are required to use an SI-Card to participate. If you don’t own your own, sign up to rent one when you register. Contactless (Air+) punching will NOT be used.


If the SI unit fails (you don’t hear a beep or see a flash), use the manual pin punch to punch your map. Before downloading, let the volunteer know what happened.

Start times

All events will have individual pre-assigned start times. You will be able to sign up for a start time approximately one week before the event.


  • Marmot Cup (2-day total time; must participate in both events in the same class) – 1st place in all competitive classes

Refund Policy

You may receive a full refund (minus fees) if you cancel by June 10. No refunds will be given after this date.

Tourist activities

The Spokane area has activities for just about everyone. From hiking, biking, and water sports to art galleries, shopping, golf, and more. Below are just a few suggestions. Get details and more ideas at

There is parking by the event staging area, where the restroom is also located. The parking is somewhat limited but if we park close to the next car, there should be enough spots. Please do not camp in the parking lot.
