Wesley Brooke is a Master of Science student at UBC who for his thesis has been studying the Knife Creek Block of the Alex Fraser Research Forest, which is on the east hand side of Highway 97 just north of Knife Creek Road and the 140 Mile area. He’s been examining trees for fire scarring. While the data gets less reliable the further back in time because fewer trees date back that far, Brooke found evidence of 22 fires between 1619 and 1943. The time between the fires varied but averaged one every 15 years.
