The story that haunts this land

Your quest begins at the Northern Life Museum & Cultural Centre in Fort Simpson, opened in 1978 and managed by the Fort Simpson Historical Society. Here, in downtown Fort Simpson and within walking distance of the Deh Cho Cultural Centre, you discover Indigenous artifacts and exhibits on the fur trade history, as well as early Nahanni gold prospectors from 1908. These initial stories immerse you in the context of the Northwest Territories' gold rush, laying the groundwork for the mysteries that await.

The journey then takes you to the Fort Simpson National Historic Site, built in 1804 by the North West Company and named Simpson in 1821. Recognized as a national historic site in 1969 by Parks Canada, its wooden remains bear witness to its central role in the fur trade and expeditions to the Nahanni Valley in the early 20th century. This site, located immediately near the Deh Cho Cultural Centre, enlightens you on the routes taken by explorers and prospectors like Frank and Willie McLeod.

Continue your investigation at the Fort Simpson Pioneer Cemetery, a historic burial ground dating from the 19th century. Accessible on foot about 1 km from downtown Fort Simpson, it holds the graves of pioneers and trappers from 1820 onwards. The often modest headstones tell tales of accidental deaths in the wilderness, echoing the tragic disappearances in the Nahanni Valley and preserving relics linked to the era of gold prospectors in the Far North.

Your itinerary then leads you to the RCMP Detachment Fort Simpson, the Royal Canadian Mounted Police post established in 1900. This central building in town, less than 1 km from the Deh Cho Cultural Centre, was involved in searches for those missing in Nahanni, particularly the McLeod brothers in 1908. The detachment's archives contain information on investigations conducted in Deadmen Valley and Headless Creek, offering you a glimpse into the efforts made to uncover the secrets of these feared places.

Finally, your journey concludes at the Fort Simpson Cenotaph, a commemorative monument erected in 1920 to honor soldiers who died in service. Located in downtown Fort Simpson, less than 500m from the starting point, it inscribes the military history of the Northwest Territories into the urban landscape. By concluding your investigation at the Fort Simpson Lookout, offering a panorama of the Mackenzie River and the historic fort, you gaze upon the waters that have seen so many fates, from trappers to gold prospectors heading to Nahanni, carrying with you the stories of an era when the Canadian Far North forged legends.
