What is ironic about the area to the east of Quesnel is that there is a legendary taboo for Indians, Shuswap (Salish) and Carrier (Athapaskan/Dene) and no doubt the Chilcotin as well.
The Indians around Quesnel and northward are Carriers while those to the south are Shuswap. Although these tribes were enemies, there were instances where they cooperated in waging war with the Chilcotin. One of the more notable battle grounds was west of Alexis Creek at a place referred to as Battle Canyon.
The cursed area extends from just slightly east of Quesnel all the way out to the highlands east of Bowron Provincial Park, not sure where the latitude is. It is a self imposed no go zone. The legend was something to the effect that harm and mayhem will beset them beyond Dragon Lake. It primarily covers all FN in central BC.
I believe the curse to be true as I witnessed an instance of bad luck to some locals early one morning on the north side of Dragon Lake. These were locals that were at the boat launch around 5 AM and drove off northward on Quesnel Hydraulic Road entering into the ditch east of Tatchell Road. The car popped out of the ditch at Tatchell sliding on it's roof for another 100' before ending up in the opposite side ditch and down a 20-30' embankment. I heard the car go by my place and I left for work about 20-25 minutes later. Emergency crews were there but no one seemed in too much of a hurry. In the 14 years that I lived there it was the only time that I knew of any locals to go to the east side of the lake.
I read a compilation of David Thompson travels long while back and it did mention some Indians in 1808 on some islands on Spectacle Lake and the outflow area at Bowron Lake, but there are no further references in time after that of Indian occupation.
The following will shed a little light on the subject.
