In reply to G4YTD:
I can’t offer much on current walking conditions, its supposed to warm up a bit over the next few days so the snow line might retreat up the hill a bit.
In the absence of any first hand infomation (and assuming you haven’t already bookmarked it) have a look at the felltop assessors report from Helvellyn over the next couple of days. Aye, I know it’s Helvellyn but it’s not that far away and the east side of Helvellyn is pretty similar in orientation/aspect etc to High Street.
The ridge looks more exposed on the map than it actually is, don’t get me wrong it’s not an east anglian field, but you can walk up it all the way without the need to cling on for dear life and without the feeling that a foot either side will send you “back to the start”. Nice walk, and if you didn’t fancy going back that way you could drop south east to Nan Bield Pass.
Suspect you might make use of the wall, looks like it will be breezy.
