Antarctica is completely controlled by governments and it would be very hard to go out alone anywhere.. they won't let you bury anyone there and they won't let you be buried.. now it's different in countries in Latin America and on the Himalayan plateau, America there are some mountains that might be worthwhile to be buried on but the government again has a lot of control there.. the best place is probably Barrow Alaska, where they have four cemeteries and where people who die in Barrow are buried there. As long as you're buried six feet deep, the permafrost thaw only reaches 2 ft deep
