Actually there are around 14 major tectonic plates - we could create another list but what would be the point? I think the origininal seven summits right or wrong would always outshine it simply because of the way it showed how ordinary people could climb ANYWHERE if they really wanted to. That's the real significance of the seven summits
Since so many people have been getting on the 7 summits list, why not add the 2 poles to it?
Now, thats what I call an Adventure Grand Slam!!

New challenge......
