The accident actually happened right at the end of Gate Gill, probably no more than 200m from the gate off the fell. We knew that we had strayed into the gully from our intended path along the ridge, but it seemed as easy to keep going down rather than try to get back to the Hall's Ridge path; we could see where we were going and were through the worst part. Three of us were carrying gear, as we had planned to do the round over a couple of days, camping out half way round. Mark was only running leg 1, never having been to Great Calva before, and fell right at the end of the valley, just before he would have left us to run back to Keswick. None of us saw what actually happened, but we understand, indirectly, that he is sitting up and drinking tea (thankfully a lot better than we had been led to expect). Needless to say the recue people really performed well; many thanks to them.
