Van Wyck Mason's "Phalanxes of Atlans" is the twenty-fourth installment of our "Lost World-Lost Race Classics" series. A lost world in the wilds of the Arctic! Only in dim legends did mankind remember Atlantis and the Lost Tribes, that is, until Victor Nelson's extraordinary adventure into the Arctic unknown. Nelson and his pal, Richard Alden, had been forced down during a flight over a previously unexplored Arctic region. Their situation was desperate. And when Alden became lost, Nelson knew it was only a matter of time before his pal would perish in the Arctic cold. But when he found traces of a bloody struggle, Nelson knew Alden had been taken—forcibly. But by who…and why? Soon Nelson found himself following a trail into a forgotten world—a world filled with prehistoric beasts and lost Atlantean civilizations. And it was in this fantastic realm that Victor Nelson soon found the adventure of a lifetime.
