 In 2013, the Friends of the Great Divide Trail re-activated the Great Divide Trail Association, a Canadian not-for-profit corporation headquartered in Calgary, Alberta, dedicated to maintaining and protecting the GDT.Since then, the volunteer run GDTA has been active in conducting maintenance and trail building throughout the length of the Great Divide Trail.Most notably, the GDTA is constructing the 50km High Rock Trail section, which replaces old roads to better link the town of Coleman with the 100km original section of the GDT built in the 80's.
