General Notes
- This is a training course, not an organized BAOC event. We do not have a park permit for this course.
- Be careful for your safety. You are on your own—tell somebody where you will be and when you expect to return.
- You are doing this at your own risk. Each participant assumes full responsibility (BAOC accepts no responsibility) for any and all injuries, losses, and damages that he or she incurs while attending or participating in this course.
- Be mindful of the general COVID-19 restrictions, and any specific restrictions that might apply to the park.
I set a tough middle-distance course at Black Diamond Mines Regional Preserve (http://www.ebparks.org/parks/black_diamond).
Background
The Junior World Orienteering Championships (JWOC (http://jwoc2020.org)) were postponed this year. As a substitute, the athletes on the U.S. Junior National Team (including BAOC’s Julia Doubson) were challenged to complete the full series of events (Sprint, Long, Relay, Middle classification, and Middle final) over a one-week period. Several BAOC club members prepared courses for Julia. This course was designed to simulate the Middle final.
Location
Coordinates for the park entrance are 37.9712023,-121.8627757. The Course Setter’s Notes (https://docs.google.com/document/d/1XBMj_O7dJn_VyDoZv1zsNCC_uRTh1Iyk6N1kJ9fDUY4/edit?usp=sharing) provide directions from there.

The “standard†sign-in/sign-out spreadsheet is here (https://docs.google.com/spreadsheets/d/1JEdfZzde9WZ7LEnsLZ8dlbRZ6bE_UBarP4UrWjXn7b8/edit?usp=sharing). Please use it.
That sheet contains a link to a webpage (https://drive.google.com/drive/folders/1ApgxCmZJpK_x3kuTSkorpz1ER9wqzIJf) that lists the map, control description, and Course Setter’s Notes. (When you get to the webpage that lists the files, double click on an item to open it. Then you can use the download icon at the top right corner of the window to download the file to your computer.)
The course details are: 2.9 km, 240 m climb, 12 controls. As described in the Course Setter’s Notes, small orange cones are used as control markers.
The map scale is 1:10,000 with 5-meter contours. You’ll see that the course goes very close to the edge of the mapped terrain—be careful!
Enjoy 😊
