Most of the Uppsala battery research group went to San Francisco for the Electrochemical Society Autumn 2013 conference. I and several others thought it would be an excellent idea to make the trip up to Yosemite National Park for a few days ahead of the conference. It was!


Mariposa grove, close to where we were staying in Wawona, just inside the National Park boundary, is home to a huge number of giant sequoias. It is great to walk around and to see these immense trees, but I had real trouble trying to take decent photos of them.

Walking all the way up the hill in Mariposa Grove takes you to the lookout at Wawona point. Our cabin, I think, was behind the near hill on the right-centre part of the image.

On our second day in Yosemite we walked up Sentinel Dome… what a view.

From Taft point. For a long time I thought I’d never get to visit Yosemite Valley, so this was more or less the moment I realised where I was!

Views from Taft point. Including nutters tightrope-walking across it.

Views to be had from Glacier point. We drove up here on our way home rather than hike up.

On our third day we took a very, very long walk - about 23 km - through Yosemite Valley floor itself.

The classic shot of Tunnel View, which surely ticks a box on the bucket list of most amateur photographers?

Views of Vernal falls – which we walked up and around on our final day in Yosemite.

Emerald Pool - at the top of Vernal Falls.

San Francisco

Ultimately I didn’t take many pictures in San Francisco – I was supposed to be working after all!

On one of our last days we were able to go and visit Alcatraz, which was excellent. The audio tour, as part of the price of admission, is particularly good – you really get a feel for what the atmosphere must have been like while it was still a working prison.

These things are quick! Could hardly keep up with it and couldn’t get close enough with the 28-75 mm lens so this is almost 100% cropped, but at least I got it…

In the words of Jeremy Clarkson, it’s just like the Humber Suspension Bridge… only smaller.

Lombard Street.

Another thing to do which we managed to fit in was to hire bikes and cycle across the Golden Gate bridge. Not that I really understand why we needed to do this – it’s loud, not particularly comfortable, and you can’t stop anywhere on the bridge without drawing abuse from other people using it for commuting purposes rather than tourism. But, you do get a good view from Marin Headlands on the other side.
