On their journey to see Aslan, where did the beavers and children stop for the night?

Mr and Mrs. Beaver and the children—minus Edmund the traitor, of course—have set out to look for Aslan. Mr. Beaver has told the children that they must meet the good lion at the Stone Table, where they are to fulfill an ancient prophecy. When the Four Thrones of Cair Paravel have been occupied by four sons of Adam and daughters of Eve, then the bad times will end in the benighted kingdom of Narnia.
But it's a long, hard journey to the Stone Table; and dangerous, too. The White Witch's spies are everywhere and the children are worried that they'll catch up with them before they reach their destination. In the meantime, everyone's thoroughly exhausted, and so the Beavers and the children find shelter in a cave where they can get some rest. However, it's not long before everyone's woken up by the sound of sleigh bells. Naturally, everyone's worried that the White Witch has arrived in her sleigh. But thankfully, it turns out to be Santa Claus, whose welcome presence is a sign that the power of the evil witch is waning in Narnia.
