As we examine the cave entrance we push aside moss and dirt, and find the initials "A.S." scratched into the cave wall! This proves it! Arne Saknussemm was here!

For the first time I understand why my uncle is so excited! Everything my uncle hoped was true! I no longer want to get home! I want to go where Saknussemm went! And farther!

Clearly Saknussemm entered this cave, but it collapsed some time in the last few centuries, after he left. Should I try to dig an opening? Or should we just use explosives? Or do something else?
