Mt Hope was first climbed in December 1964 by Mike Cousins and Keith Holmes from BAS, then got its second and third ascents in January 1970 by more BAS personnel.
I'd be interested to hear what UKCers think of the issue of sovereignty over the 'British Antarctic Territory' and whether this peak is really your highest- do you recognise it as genuinely British territory? Or is it a leftover of imperial Britain, an anachronism. No one owns Antarctica, right? That's what I'm always hearing. Fact is, most of the world does not recognise these claims (including my own Australian 42%).
Or should your highest mountain be Mt Paget on South Georgia? Which, incidentally is much more difficult and impressive than either Mt Hope or Ben Nevis.
