Ice Giant's Lair

Publisher's blurb:

Walls of ice form this giant’s lair. A bearskin on loose hay makes a bed over the cold ice floor. Nearby, a central cooking fire is decorated with engraved mammoth tusks and bones from prior meals.
A network of crystalline caverns, fortified with sharpened stakes and burning torches, forms this frozen lair. Running through it is a stream, while slippery ice bridges span high above.
