Went over Garburn last night and it was very washed out in an entertaining and challenging wsy with deep ruts and drifts of boulders. Going up from Troutbeck would take some serious technique and fitness to clear with out a dab or walk due. Coming down in to Kentmere was great and not anywhere near as rutted until you get to the last part of the trail where it comes out at the farmin Kentmere where the trail had simply been stolen and replaced with giant ruts and boulders.
In summary I can conclude that there has been some serious water erosion!
It is interesting to see trails ever changing with the ravages of the weather, and such dramatic changes as that.
