P600.org – An excellent collection of mountain images and trip reports from across the world, run by Deividas Valaitis, a friend of Gunung Bagging and someone who has helped the site greatly by developing a bespoke maps plugin for us. The focus is on mountains with a prominence of 600 metres or more, hence the name.
