FWIW, B.C. Wildfire crews were in clearing the deadfall from the Cheakamus Lake trail yesterday. It's now jogger stroller friendly (for the time being). I only went as far as the lakehead but the crews were carrying on to Singing Pass site so I imagine the whole thing is good for wheels now.
What deadfall? We were there this past weekend and there were two large logs (one about a metre diameter) together across the trail which looked like they'd been there for a year or so, judging from the well-beaten path around them. And about two other small trees down on the trail.
