Rosaryville

Pre-registration is required and will open Monday Nov. 16 at noon (our permit has been approved!).

There will not be day-of registration.

Come out and enjoy a full set of courses designed by Mike and Pam Dvorsky on the updated Rosaryville map – also updated by them this fall – in this classic fall orienteering event at Rosaryville State Park, Maryland. (course stats and course setter comments below).

This event requires on-line pre-registration which will open on Monday, 16 November at 12 noon. QOC’s COVID risk reduction protocols, as also enumerated here, are in effect. Please read these guidelines carefully, particularly keeping in mind the need for participants to bring their own water for all their hydration needs before, during, and after their runs/walks.

When you arrive, the map pick-up will be at pavilion # 2 North of the parking lot. The start, finish and download are all nearby (but appropriately distanced to avoid clusters of people). Please make an effort to click and move on from these sites as consideration to others.

The start location for beginner courses will be separate from the advanced courses to minimize contact. Beginner courses will start just north of the traffic circle / southwest of the parking lot, and advanced courses will start northeast of the parking lot.

In addition to our regular classic courses, this event will feature a different navigational challenge: Amateur Radio Direction Finding. In ARDF, you use directional radio receivers to locate beacons in the woods. Learn more about the event here, and to register, click on this link, which will also become active at noon on Monday. [Friday evening note: cancellations have just opened up one 10am and one 12:30pm ARDF slot.]

Any youth or large groups attending, although you will be pre-registering online, please contact the Event Director of your plans and numbers for his situational awareness.

Other points:

  • PROPERLY WORN MASKS ARE REQUIRED at all times when near registration and epunch areas and their volunteers.
  • Water will not provided in accordance with QOC COVID-19 risk reduction policies. Please plan for your own hydration needs before, during, and after your run/walk.
  • We encourage everyone to download and use both the Maryland and Virginia COVID exposure notification apps on their mobile phones.
  • Pets are permitted in the park but must be on the leash at all times.
  • Port-a-johns will be on site.

ABOUT THE MAP: The map has had a major update in the fall of 2020 by Mike and Pam Dvorsky. This is likely the first substantive update since at least 2015. For those of you who are used to the old Rosaryville map, you may be in for a shock. On the new map, all trails, open areas, landforms, streams, contours, water features, man-made features are accurate. Vegetation has been updated and is generally accurate, but still requires more work. Rootstocks and movable man-made objects (mostly horse jumps that are stored on the edge of wood-lines) are not marked on the map. Permanent horse jumps are marked with a black “X”. It is a beautiful park with several distinct micro-climates and flora zones; ranging from an area we nicknamed “Jurassic Park,” to trail rich zones, to fern filled valleys, to impassable overgrown thickets, to open forests. This park offers as wide a range of terrain as we have seen in a single park. We hope our work will result in a better- quality orienteering experience for you at Rosaryville.
In general, you will see a wide range of runnability at Rosaryville. There are pockets that are dense with vines, briars and saplings that will make passage extremely difficult, if you are not on a trail, yet 10 yards away it could be open and runnable woods. This entire park is a trail-rich environment with horse, mountain bike and hiking trails. Years ago, this was a farmland community and evidence of old buildings, barns, roads, and old trash dumps can be found throughout the park. Old roads are generally marked as Rides. Trash dumps (old cars, refrigerators, farm implements, etc.) are marked with a black X. In the central area of the park is Mount Airy Mansion, which dates back to the mid-1700s and is part of the park. It is rented out for special occasions and the grounds are open to the public. It is OK to use the trails and roads in this area. Generally, the area of woods just outside the Mount Airy grounds is thick with vegetation so trails are the best option through that area.
The terrain is classic ridge and valley, with broad, flat ridges and deeply incised watercourses. Along the streams are many side reentrants. Climb in this park is mild to moderate, except around streams where embankments tend to be very steep. Marshy areas and reentrants may be bone dry or boot-sucking mud depending on the amount of rain we get during the week prior to the meet.
You will probably encounter horse riders and mountain bikers during your run. Some horses startle easily if they don’t know you are there. Please step to the side of the trail and let the horses pass you. Try not to run by a horse or come up from behind them. Mountain bikers will usually slow down as they approach you and call out which side they want to pass you on. Again, just step off the trail momentarily while they pass you. Being courteous is the key! All trails are accurately shown on the map and are generally in good condition, though all trails are covered with fallen leaves and can be more difficult to see this time of year, especially the indistinct trails. The mountain bike trails are very distinct and smooth, where the horse trails often are beaten up and muddy. If there is recent heavy rain, many flat areas and trails will be wet, muddy and marshy. Please make sure to tighten your orienteering shoes or you might lose them in the mud. Several trails are marked as indistinct. If you are on an indistinct trail, you can follow it fairly well if you pay attention, but if you run across it you may not notice it.
There are many large rootstocks in the woods, but none are marked on the map and none are used for controls. Do not rely on rootstocks for navigation.
Enjoy, and may the force be with you.

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 will be loaned one 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 (such as car keys) when borrowing a compass or epunch.
  • Please note that normally there are no refunds (unless we cancel the event).
  • Free beginner instruction is always available - just ask at the registration table. While COVID-19 policies are in effect, please check out instructional videos online such as this one in lieu of in-person/at-event instruction.
