My deapest sympathy to those who have affected by these tragic losses of life. It is always sad to hear of any serious accident in the Fells and a concern that it is one particular route.
Jack's Rake is a very fine grade one scamble which I do usually once a year. On the last visit I did note that when testing the handholds a few rocks were loose. This is something I had previously not experienced and it made me concentrate harder than usual. The three points of contact rule is essential for sections of the Rake. There is some exposure early on in the ascent. I would not recommend it for a first taste of scrambling, but with experience under your belt it is a classic that can be achieved. The Rake is obviously a channel for some running water after wet conditions. Extra care thus required or better still wait for a dry period, if such a thing exits in Lakeland.
Thanks as always to Mountain Rescue and the other emergency services.

Here, Here! to Chris Boothman's comments. I would like to know from at what point(s) exactly the unfortunates fell. For much of the way - say up to the third ash tree - albeit steep one is protected by a parapet of rock, but especially when wet great care is needed. Beyond that point the terrain eases, becoming open and airy; but on my last occasion there, in warm dry weather, two persons coming up behind me with a teenager were rather cavalier about hopping down from one exposed ledge to another and hoping not to be 'officious' I did suggest more care - an inadvertent trip could be fatal at that point. Especially with youngsters use of a short, say 50 feet, 7mm 'scramble' rope is not a bad idea, on ascent or descent, and there are plenty of easy belay opportunities.
