We spent the whole of the hottest and sunniest day of 2016 (so far) climbing in perpetual shade, the only climbers on Cywarch's vast north face on a totally perfect day. But on such a bright day, the sun was my worst enemy. The lighting was very uneven, so trying to get an even and balanced shot of a subject in shadow was difficult. This was my best effort.
Incidentally, this was my third ascent of Acheron, almost 34 years to the day since my first one when it was simply graded VS. First led on sight by A.J.J. Moulham in 1956, it's a stunning example of brilliant route finding up a huge steep rib. The current HVS grading, with revised pitch grades of 4c, 4c, 4c, 4c, 5a and 4b seems to be pretty spot on - and no amount of training on a climbing wall will ever prepare you for the subtle intricacy of the flared crux chimney. :-)
