Maps & Courses

Information about the competition maps will be posted closer to the event. General terrain information may be found below.

For the Saturday middle distance and Sunday long distance races, the full range of OUSA courses from white through blue will be offered, with competition in the normal OUSA classes, open classes for each course color, and Interscholastic and Intercollegiate Classes. Preliminary course stats for the middle and long distance events, subject to change, are posted below.

The Saturday afternoon relay will be an unsanctioned event with 3 legs, each up to 3km long, of yellow/orange or orange/advanced difficulty. There will be categories for both club and school teams and, within those, subcategories of competition between similarly strong teams based on an age/gender points system. Details are yet to be finalized - watch this space.

Beaver Dam Run, Marine Corps Base Quantico
General Terrain Description 
Mixed pine and hardwood forest with several large grassy fields; generally open and runnable, but with some variability due to scattered patches of vegetation and deadfall affecting visibility, some saplings of variable density and scattered areas of greenbrier and brambles. The map is bisected by Beaver Dam Creek, which is, under normal conditions, wide but crossable nearly everywhere. Several footbridges allow the stream to be crossed without getting wet feet. An extensive network of trails and rides exists, along with a large number of small depressions and knolls. 

Detailed Map & Course Notes
Day 1 map sample
There are several features unique to this area as an active military training area: Metal posts painted red and white are used as land navigation markers – they are indicated by a black X on the map. Several areas of obstacle courses exist – the obstacles are also indicated by a black X on the map. Some of the obstacles are on trails making for an unusual (and difficult to read) combination of black X overlaid on the trail symbol. Always be on the lookout for random unmapped sections of barbed wire and concertina wire anywhere in the terrain.
Important: Several large out-of-bounds areas are designated on the map – these are areas of live explosives and must be avoided. They are marked by red flagging in the field. In other areas orienteers will encounter “Danger Do Not Enter” Signs. These signs may be safely ignored if they are not mapped as out-of-bounds on the map.

Hazards: There are long sections of single strand barbed wire that are difficult to see while running in the forest. Many of these have been marked with short pieces of red and blue flagging tape to aid visibility.

Advanced course runners may also encounter ominous signs (see photo) along these fence lines that can be safely ignored. The demolition ranges are not in use this weekend and we have permission to ignore these signs.  However, it is imperative that all orienteers stay out of the Out of Bounds areas delineated on your maps. These areas may have unexploded ordnance and are marked with a continuous strand of very distinctive blue/white/yellow flagging tape – these areas may not be entered at any time.

Obstacle Courses: This is an active training base used by the US Marines.  You will encounter many forms of obstacles and other training facilities scattered throughout the area. Please do not enter, climb on or interact with these facilities in any way. If you find man-made objects on the ground, please leave them there. There may be sharp or explosive objects left over from prior training exercises – it is best not to touch them.
