Unexplored!

A rambunctious rodeo in the shadow of the high Sierras launches three teenage friends, a youthful Geological Survey assistant, and a seasoned prospector into an unforgettable summer. Amid the dust‑caked corral and the crack of spurs, the boys swap jokes and daring bets before swapping their boots for pack‑burros and heading into uncharted wilderness. Their guide, a weather‑worn miner who knows every canyon trail, promises a journey that will test their grit and curiosity alike.

The expedition unfolds across roaring rivers, glittering trout streams, and towering sequoia groves, with bears patrolling the woods and the Forest Service Air Patrol swooping overhead. As they set up camp, study rock layers, and follow the echo of distant earthquakes, the group begins to piece together the ancient story of the land, from dinosaur‑age fossils to the forces that carved today’s dramatic canyons. Along the way, they confront sudden avalanches, mysterious caves, and the ever‑present thrill of the unknown, learning that the greatest discoveries often lie just beyond the next ridge.
