Great Falls Fall Color

Welcome back to C&O NHP! Once again, due to park regulations we require advance registration with payment, and we are expecting to sell out. Registration is now open closed; click here when ready to register. If you have registered but will not be able to attend, please notify us in advance so others can attend. If people cancel in advance we may release some extra registrations. Whether or not that happens, there will be no day-of registration at the event. There will be compasses and epunches available to those who requested them during pre-registration, but GPS watches will not be available at this event.

On Sunday, only pre-registered orienteers will be able to start on their course, anytime between 11 - 1:30, and must be back no later than 3pm. For planning purposes: from our registration area, there's a ~5-10 minute walk of about 600 meters to the start shared by all courses, and a walk back of about 400 meters from the (shared) finish.

Course Information: Course stats and course setter comments are now posted below. Note that there are officially 3 approved courses (beginner, intermediate, and advanced; see note about courses in course setter comments). These courses are carefully designed to avoid areas that the National Park Service has designated as sensitive.

Speaking of sensitive areas, the NPS has asked us to remind all participants of the following:

  • Participants should follow compass bearings as close as possible. Participants should not take shortcuts: approved routes are designed specifically to avoid sensitive habitats and known invasive plant populations that may facilitate human-facilitated spread of seeds and berries.
  • Participants should avoid any and all standing water, including seeps, springs, wetlands, and streams. Amphibian diseases have been documented in the area, and human-facilitated movement of such fungal pathogens from habitat to habitat can cause massive die-offs in amphibian species.
  • All participants must avoid stepping in streams and should try to minimize impacts to stream bank vegetation and soils.

Course NotesClassic

As stated above there are three official courses. The Beginner course map will be at 1:7500 scale while Intermediate and Advanced course maps will be 1:10,000; contour interval is 5m on all maps.

For the Advanced course, the length is on the long side for those runners who usually run Green or Brown. As in previous years, if you start this course and feel for safety reasons you won't be able to complete it fully, there will be a recommended alternative.

First, a few comments about the map. The map has been minimally updated, generally in areas around control locations and where new vegetation may affect route choices. he light green on the map is almost in all cases young saplings that may or may not slow the runner. At this time of the year visibility in those areas is minimally affected. There will be only a few short legs on the Advanced course where visibility through these saplings may be a problem and cause you to alter your route, but, overall the forest is open and runnable. Rootstocks mapped are at least 1 m in size, older more degraded ones were removed. A large segment in the middle of the map is cross-hatched, i.e. out of bounds. It is permissible to transverse this area on a trail, but NOT permissible to cross this area off trail. Also, the roads bordering the park are OUT OF BOUNDS and are NOT valid route choices. Runners on the Beginner and Intermediate courses will not have this temptation to use the road, but runners on the Advanced course may be tempted towards the end of their course, nonetheless, please don’t use the road.

Now, specific course comments. On the Beginner course, the first leg of your course is along an indistinct trail, this portion will have streamers to get you started. On the Intermediate course, as stated previously, it is OK to cross the cross-hatched area in the middle of the map on an established trail, but not off trail. You may have route choices where the trail though the cross-hatched area is an option. On the Advanced course, if you feel you are tired and unable to complete the entire course, as a safety precaution, the course loops past the finish giving you an obvious way to end your run. And again, please do not use the park entrance road as a route choice option.
As always, enjoy and have fun.

Important Notes
  • If you wish to become a QOC member you should join online in advance via this webpage (which also explains the member benefits). Membership is completely optional.
  • Most of our events use an 'epunch' timing chip for electronic timing. Individuals or groups without their own epunch pay a higher entry fee (see above), which includes the loan of an epunch for that event. Loaned epunches that are lost incur a $40 replacement fee. Epunches (also known as SI-cards or finger sticks) can be purchased from online vendors as described here.
  • Former QOC members who have let their membership lapse pay non-member fees.
  • Compasses are available at no charge, but if lost incur a $15 replacement fee.
  • Please provide collateral (driver's license or car keys) when borrowing a compass or epunch.
  • For additional safety, whistles are available for sale at $1/each.
  • Free beginner instruction is always available - just ask at the registration table.
