January 6

Welcome to orienteering in 2013! The registration area for this event will be in Patapsco Valley State Park, Pavilion 501, not far from the entry gate house for the McKeldin area, and close to the only bathroom facility that will be open in the park. We fully expect that winter will have arrived by the day of the meet, and we will have a fire going in the pavilion grill and sausages and marshmallows available for roasting along with hot chocolate and coffee. We hope to see lots of folks out to experience McKeldin's hilly terrain and the challenging courses that Mark and Patti Mace have planned.

McKeldin Any youth or large groups attending, please contact the Event Director so that we can coordinate pre-registration for your group; the group registration and waiver form is part of the information on our Group Leaders page.

E-punching will be in use, and course details are now posted. If you are considering trying a harder level course than usual, you might want to consider it carefully since these courses have a greater amount of climb due to the nature of this terrain. Course notes are posted below. Note: there is a park entrance fee that will be collected ($2 per vehicle for MD residents, $4 per vehicle for others).

Course NotesClassic Orienteering

The terrain is runnable at speed, except in some areas where dried Japanese stiltgrass obscures rocks and deadfall from view somewhat. Visibility will be very high unless Mother Nature graces us with heavy fog or a blizzard on January 6th. The map has been updated recently by John Blaisdell and Ted Good. Some now decayed rootstocks has been removed and new ones added where they were encountered during course setting but competitors may still see some unmapped rootstocks created by the storms of 2012.

For Green, Red and Blue runners: your courses will cross Marriottsville Road. Please be careful of oncoming vehicles.

Everyone: check control codes to avoid punching the wrong control; some controlsĀ are close together and could trick the unwary.

The printed maps will be 8.5 X 11 inches for all courses. The map scale will be 1:5,000 for white and yellow and 1:10,000 for all other courses. The contour interval will be 5m.
