Right, so I'm still not entirely sure what I saw on the 15th of October while hiking near Kinder Scout. Was heading back toward Edale around 4:30pm when the light was getting proper dodgy, and I noticed something massive moving through the bracken about 200 metres away across the valley.
It was massive - easily 7 or 8 feet tall - and covered in dark brown fur. The gait was all wrong for a bear or anything normal. Long arms, distinctive hunch to the shoulders. My mate Dave was with me and he saw it too, though he reckons it was "probably just a person in fancy dress" which is bollocks because we were miles from anywhere.
The weird bit: when it noticed us, it stopped dead for about 10 seconds, then just... loped off into the mist. Properly loped. No human could move like that through that terrain. We didn't get photos because we were too gobsmacked, but I've got the exact GPS coordinates if anyone wants to investigate the area.
