There will be only one White, Yellow, Orange, Red and Blue course each day. Classes running Brown and Green courses will be split into X and Y. 

Green X = M50+, M55+, M60+
Green Y = M-18, M-Green, F-20, F35+, F40+, F45+, F50+ and F-Green

We reserve the right to modify these class/course splits based on registration numbers to balance the number of participants in the XY pairings. 


Day 1, 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 Beaverdam Creek, which is 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.

Day 2, Marine Corps Base Quantico

General Terrain Description
The area is typical Mid-Atlantic rolling spur and reentrant terrain with ridges ranging in height from 30 to 50 meters. There are areas of complex ditch and gully networks interspersed with broad, vague spurs and hilltops. This area has very few trails with the exception of a gravel road that bisects the area and little to no rock feature. The forest is mixed pine and hardwood forest; generally very open and runnable, but with some variability due to scattered patches of holly trees which affect visibility, some saplings of variable density and small amounts of greenbrier and brambles. The area is bisected by a major stream network, which is easily crossable in all areas, although the stream valleys often host much thicker vegetation than the hilltops.

Detailed Map & Course Notes
Day 2 map sample
Some specific notes about the mapping style. Point features such as knolls, cup depressions, and cairns are generally quite small, but distinctive due to the lack of other non-contour features. Knolls are typically mounds of dirt formed from rotted rootstocks and cup depression are frequently a hole left behind by the toppled tree. Rootstocks are marked with the green X symbol. Only prominent rootstocks over one meter have been mapped. Where the fallen tree trunk is particularly large and in impediment to running, it has been marked on the map with a green line extending from the X. Vegetation is fairly kind here – both light green and medium green are traversable, although slower than white woods, with the main impediment being loss of visibility. These areas are typically dense saplings. Slash green is used to denote areas of significant deadfall. The Marines use this area for land navigation, so many of the black Xs on the map are used to show their control markers, which consist of a head height red pole with a red ammunition box attached to the top. In some locations, the black Xs may also denote large pieces of trash such as 55 gallon drums. Indistinct rides are very indistinct – especially with the leaf cover in late fall, you should not expect to these to be very evident in the terrain. The difference between intermittent streams and ditches or gullies is always a bit subjective and dependent on the season. How wet or dry the ditches and intermittent streams are will be dependent on the weather leading up to the event. 

Course Setter Notes:
The walk to the start from the arena is approximately 200 meters along a small trail. Please stay on the trail – the forest to both sides of the trail is part of the competition area!  
Due to the lack of trails in this area, the white and yellow courses will be somewhat more difficult than Day 1, and will take advantage of the significant stream network as handrails as well as trails. The white course’s leg 3 to 4 will be entirely streamered through terrain using orange streamers. This will be marked on the maps with a dashed line between control 3 and 4 which follows the path of the streamers. 
Due to the constraints of the finish and start areas, all runners on Orange through Blue will have their last one to two controls in a small area approaching the finish. Please check your controls codes carefully and be courtesy to the other runners in the forest in this busy area. 
Please be aware that as this is an active military training area, we have found some concertina wire in the terrain. Where we found it, we have marked it with orange streamers, but be alert that there may be more that we did not run across.
