Cleaning up the sites has been a priority for quite a while in the Australian territories. Some structures (Mawson's camp and so on) are preserved for historical value.
Being a continent it has mountain ranges and valley (one of them is under 4km of ice). All the Arctic has are reaches, sastrugi and deep water with the odd island sticking out. (That's not a criticism of the Arctic, it's just that Antarctica has always interested me more)
I like a place that has Mt Terror as a major landmark
