After a hiatus of many years, BAOC will be returning to Annadel State Park on Sunday, November 11. This will be a special day — a sweet homecoming for long-time members of BAOC, and newer members will get to see what the fuss is about. Annadel was used for the U.S. Orienteering Championships in 1989, and represents some of the best orienteering terrain in Northern California. There are intricate mining areas, broad meadows, and slopes with patchworks of forest and small clearings. Parts of Annadel can be steep, but as a whole, Annadel is not as physically rugged as some other BAOC orienteering venues.

The person who deserves the most credit for obtaining the event permit is Judy Koehler. She has always had her eye out for an opportunity to get back into Annadel. Recently, with the state budget crisis, Sonoma County Regional Parks (which we have had a good relationship with for many years) took over management of Annadel. Judy went through many rounds of negotiations before we were able to obtain a permit. – Gary Kraght

Bill and Heidi Cusworth will be setting five courses: White, Yellow, Orange, Brown, and Green/Red. The map is old, so participants on the advanced courses will need to make allowances for possible changes in vegetation and trails. Presumably the contours will remain accurate. If this event goes well and the land owner decides to have a long-term relationship with orienteering again, the Annadel map will be made current for 2013.

The standard time schedule applies:


We will meet at the northeast entrance parking lot for Spring Lake County Park (which is adjacent to Annadel State Park). This is different than the Oak Knolls Picnic Area that we usually use for Spring Lake events. (See the Map of Upcoming Events for the location.)

There is a $7 fee per car to enter the park.


Bill and Heidi Cusworth are the course setters. They have spent a lot of effort on the course design, including making map corrections. But don't expect map perfection. The Annadel map is many years old, and some trails and vegetation has changed in the meantime. Just go with the flow, and have fun! There will be five courses, as follows:

   Course       Length    Climb
   White        2.8 km     35 m
   Yellow       3.6 km     55 m
   Orange       4.4 km    105 m
   Brown        3.8 km    165 m
   Green/Red    6.4 km    275 m

All courses will have E-punch. Rental E-sticks will be available at registration.

There is a 1.3 km walk to the Start from registration, with 135 m of climb. Allow 30 minutes, or more if you are a slow walker. There will be plenty of water at the start. The Finish is next to registration and parking.


We really need volunteer help! If you are planning to come, please consider spending some volunteer time. We need several volunteers to help at the Start, one or two E-punch volunteers (no prior experience needed), a number of control-pickup people, etc. If you think you might be able to help with control pickup, keep your bib numbers handy, because you will also need them for control pickup. If you may be willing to volunteer some time, please send an email.
