It's seems strange to me how some routes have gained the name "Pass" and other haven't been so fortunate. And if ever a route linking two valleys deserved it then this is the prime example. This is forms an obvious link between Borrowdale and Grasmere. The 'edge' itself falls just short of the 2000ft mark and the way across the highest section could be very confusing during cloudy conditions. Anyone going astray along here could well find themselves wandering into the boggy ground leading to Ullscarf. In contrast to this, each end of the route has a well defined path and dare I say it is quite obvious.
On a personal note:
Quite a few years ago (1997 to be precise) I walked right over this route from Stonethwaite to Grasmere, and unfortunately for me at the time, I walked straight back again. About a month prior to this I suffered a sprained ankle which I mistakenly thought was back to full strength again. On the return journey it took me over four hours to walk from Greenup Edge back down to Stonethwaite, every step of which was agony.
