Course setter's notes

Temp-O Saturday June 15, Phillips Academy Campus, Andover MA

Map scale 1:4000, contours 1.5 m
7 stations, 5 questions each

Maps oriented to the direction you are facing (median between Alpha and Foxtrot flags). Zero answers are possible. Maximum time 2min 30 seconds (150 seconds) per station. Penalty for incorrect answer 30 seconds.

Tolerance for zeros: In order for the answer to be zero (none of the flags) the closest flag has to be either:

  1. On the wrong feature
  2. On the wrong side (at least 90° off from the described direction) of the correct feature OR
  3. If on the right side of the right feature at least 5 m from the correct location

According to the vetter all zeros are obvious.

PA-Campus is a private school campus with a mix of trees, bushes, buildings, and some forested patches.

Total distance traversed will be 1.2 km. There will be a water station at midway point and at finish.

IN ORDER TO MAKE THE RACE FAIR FOR ALL CONTESTANTS, WE HAVE DECIDED TO INCLUDE A QUARANTINE FOR THE COMPETITORS. The quarantine opens at 10:00 am and closes at 10:30 am. All competitors must check in to the quarantine by 10:30 am. Competitors not checked in to quarantine by 10:30 am will not be allowed to enter quarantine area and will not be eligible to win US championship awards. The first start will be at 10:45 am.

Pre-O Sunday June 16, Houghton’s Pond, Milton MA

Map Scale 1:4000, contours 5m

19 controls, total distance covered 640 m, maximum time 90 min for open and 105 minutes for paralympic. One timed control station with 3 questions. Maximum time for timed control 90 seconds, penalty for wrong answer 60 seconds. On the timed control station there are no Zero answers.

While the base contour interval is 5m a lot of form-lines are used to describe the shape of the terrain. These form-lines are not always 2.5 m from the closest contour line, and two separate form lines do not necessarily indicate the same elevation. Best effort has been made to keep two close-by form lines in alignment with each other. This area is a forested patch with a lot of rock features. By New England standards the visibility is great, and the vegetation only obscures things surprisingly mildly. Trust your reading of contour lines and use rock features where ever possible.

Viewing direction is given in the control description where ever applicable. Viewing stations are marked with small orange cones in the woods. Parallax is possible, be careful. For A controls (flag (A) or no flag(Z)) no viewing station is specified in the woods. In those controls, find the best viewing station you can, the question is whether there is a flag in the correct location or not.

The allowed path contains two parts, a shoulder of a road, and a path indicated by sprint symbol 506 (unpaved footpath). This is the symbol for a path that has brown infill and dashed black sides. You are only allowed on the shoulder of the road and the parts of the trail marked with symbol 506. On the road you need to stay on the North shoulder (the shoulder you start on). There will be course marshals making sure you stay on the allowed path and allowed part of the shoulder. Where the trail changes from allowed to not allowed there will be tape in the woods indicating forbidden part. Each competitor will be issued a pin punch and a control card. The control card should be punched at the viewing stations.

Each competitor should also have an SI-card to time themselves on the Pre-O course. First start is at 9:30 am. After punching finish, competitors are guided to the timed control. After timed control the competitors will be shuttled back to the NEOC picnic site. Remember to download your SI-card upon arrival back to the picnic site.

There are two potentially challenging parts for competitors in wheelchairs along the way. If we have wheelchair competitors, we will make sure they get help past the difficult parts.

Tolerance for zeros: In order for the answer to be zero (none of the flags) the closest flag has to be either:

  1. On the wrong feature
  2. On the wrong side (at least 90° off from the described direction) of the correct feature OR
  3. If on the right side of the right feature at least 5 m from the correct location

According to the vetter all zeros are also obvious in the PreO.

Thank you for Jim Crawford and Richard Y. Ebright for acting as course vetters. GOOD LUCK!
