I was out checking an area this weekend, as well. Just south of where BC Witness was. I went to the Chilliwack River Valley. Tried to get up to Foley Lake, but there was still a foot and a half of snow. A small avalanche blocked the FSR. ATV's could get over it but the snow was too deep and soft for my truck. I parked it and my wife and I hiked the 5 km up to the lake, instead. After we got back to the vehicle, we went to a forestry campground nearby (no snow there), where a witness had told me that he had experiences nearly every time he camped there. Bipedal footfalls within the campground, pine cone throwing, etc. A beautiful area with tall Pine trees and mossy undergrowth outside the camping boundaries. Like walking on carpet. Definitely going to have to spend a weekend or two there.
