When it comes to northern wildernesses there are few accessible places that compare with Alaska as a state, and I have been fortunate to have some exceptional wildlife experiences to photograph in front of me there: I will never forget a 10 minute spell, lying on a beach with two female bears literally hammering into one another and fearing that it might end in tragedy.  Bears have always been at the heart of my visits here but the autumnal colours of Denali National Park and photographing incredibly cute sea otters resting on ice are also memories I will long cherish too.
