This anthology issue contains at least two science fiction stories. The first story depicts alien beings engaged in strength-testing and combat preparation for inter-world conflict, with their civilization experiencing rapid acceleration of their young males' warlike development. The second story, "The Yodler of Yognasi," follows mountaineer Williard Merrit's attempt to climb Mount Sugarina, where he encounters the mythical Yodler—a creature whose horn-call creates landslides—and discovers it is actually a being from an alien civilization that arrived twenty-two cycles ago; the aliens have established a hidden city on the cosmic rays, don't eat or breathe like Earth people, and invite the climber to visit their manufactured world where they offer him freedom to come and go as he pleases.

Contains 6 stories
Dark Side of the Moon
5 pp · Science Fiction

A greedy treasure hunter named Fry stumbles upon what he believes is the galaxy's greatest fortune hidden on the dark side of the moon—only to discover that his newfound riches come with a sinister catch that turns his dream of wealth into something far more complicated. Written with the inventive sci-fi premise that defined 1957's wildest pulp imagination, "Dark Side of the Moon" flips the script on fortune-seeking in ways you won't see coming.

Behind the Eight Ball
5 pp · Science Fiction

Jed Stone, forever unlucky and dubbed "Eight-Ball" for his perpetual misfortune, finally believes he's about to accomplish something big—but as he sets his plan in motion, he unwittingly triggers catastrophe on a microscopic world that exists right beneath his nose. When an entire civilization of beings faces annihilation from a rolling mass they cannot stop, they have no idea that their doom originates from a single moment in Jed's ordinary life. Written with a deft touch of cosmic irony, "Behind the Eight Ball" reminds us that even the smallest action in one universe can reshape the fate of countless worlds.

The Night the Grand Canyon Disappeared
3 pp · Science Fiction

When the Grand Canyon mysteriously fills overnight with an impenetrable alien material, scientists from around the world are called together to solve the impossible—but the real discovery waiting beneath may teach humanity something far more valuable than any analysis ever could. Written with genuine wonder about first contact and the power of cooperation, this 1957 science fiction gem reveals that sometimes the greatest mysteries are designed with purpose.

The Yodler of Yognasi
5 pp · Science Fiction

When mountain climber Williard Merrit sets out to conquer Mount Sugarina against all warnings, he dismisses the legend of the Yodler—a mysterious figure whose horn-blowing supposedly triggers devastating landslides—as mere folklore. But as his expedition encounters the very phenomena he sought to debunk, the line between scientific skepticism and supernatural reality grows dangerously thin. A tale of ambition, mystery, and the mountain's ancient guardianship from *Mysteries of Unexplored Worlds* #2.

Objective Moon
5 pp · Science Fiction
The Tiny World
2 pp · Science Fiction

Karl Crowder, owner of a flea circus, insists that his performing fleas possess genuine emotions and consciousness—that they fall in love, scheme, and feel jealousy just like people. When his skeptical companion challenges him, Karl points to the drama unfolding in the circus ring: two fleas in love, a rival sabotaging their act, and a loyalty test that seems to prove his point. But as the companion suggests, perhaps Karl's interpretation says more about his own need to hold dominion over a world he can control than about what the tiny performers actually feel.
