BKB is just suffering from over use, it’s getting very eroded, particularly where they’ve cleared the trees. The bottom bit’s fine, but the top’s a bit of a mess, not remotely sustainable IMO.
Of course this is partly because th eend bit is new and the old bit is, er, old. But also the new bit was all built to a standard, with smooth sloping water run-offs where it could be managed, and swoopy profiling to minimise braking and all that stuff.
Not sure what is happening with the trail volunteer work, but I would guess they will be keen to do some remedial work on the top bit of BKB soon.
At least the logging on BKB has mostly restored the trail to one line, instead of all the straight-lining that had sprung up.
I’s a bit random and ad-hoc – but if you’re near Regurgitator why not spend a few minutes doing a bit of tidying up – or are the logs too big?
