On the now at last :-) From home it was 5 miles ride on tarmac before picking up a forestry/wind farm track for another 5 miles, then when I couldn't get any higher on the bike, it was a change to running shoes for a stiff but pretty short hoof to Queensberry's summit. It was fab to spend 3 hours soaking up the sun, making some useful vitamin D and attempting to put some colour into my pasty legs. The ride on the track was sketchy at times, but once again, my venerable old Dawes touring bike showed its merit.
The remaining depth on the snow patch is perhaps 1 metre at most, maybe 5 metres in height, and less than 100 metres long. A small chance it'll last until the beginning of May, but it's melting away very fast.
