I don't think you can view those particular photos without a facebook account.
Please note that the photos were taken and posted by the person doing some of the field work on the possible long maps and the sprint map. They are his photos and his facebook account.
They are attractive photos for sure but as far as I know they were posted without the authority of the Ottawa Orienteering Club (which he didn't need) but the club probably would have asked him to be less specific about the location of the areas.
The OOC will be including those photos and other information on the COC 2010 website
http://www.ottawaoc.ca/COC2010/ in the near future.
Plans for COC 2010 are coming along nicely. A real orienteering treat is in store for those who come to Ottawa next August.
