In reply to The Lemming:
I can't compete with the best on here, but I'm quite pleased with this one, from last Wednesday:

I'd had a great climb on the South Rosa slabs with my father, and stopped off for a quick dip in the Glenrosa water on the way back out.
After jumping in and swimming around the pool a couple of times, I got out and started to get dry - then noticed this young adder (about as long as my hand), apparently stuck in an eddy below the small waterfall which fed the pool. It appeared to be trying to break free, but was getting slower and slower each cycle, and being sucked under by a mini-whirlpool for longer each time it passed it.
I thought it was probably going to end up drowning, so I fished it out with my helmet and left it on the warm, sunny granite to heat up (a good few metres from where I was getting dressed!)
It didn't move much at first, and I wondered whether I had been too late, but it gradually perked up and started watching me as I moved around it taking photos, rising defensively a little, perhaps wondering how much of a meal I'd make.
A beautiful creature, but I'm glad I didn't brush against it in the pool!
