From Dark Horse:
January 25, 1931: an expedition team arrives at a campsite in Antarctica to find its crew of men and sled dogs strewn and dead. But a still more horrific sight is the star-shaped mound of snow nearby for under its five points is a grave and what lies beneath is not human.
At the Mountains of Madness is a journey into the core of Lovecraft's mythos. The deep caverns and even deeper times of the inhospitable continent are where the secret history of our planet is preserved. Amidst the ruins of its first civilization, built by the alien Elder Things with the help of their bioengineered monstrosities, the shoggoths.
