THE MIGHTY COLORADO RIVER...as wild and unpredictable as its thundering rapids...as relentless as its first daring explorers. THE 1869 POWELL EXPEDITION...deep in a chasm of roaring water and soaring stone and at a deadly stretch of river now named Separation Rapids, three desperate men abandoned the expedition after months of unspeakable hardships and near starvation. But only one of the three could survive high up on the wild, uncharted North Rim. WILLIAM DUNN...a mountain man forever haunted by guilt and driven by the love of extraordinary women will cast his fate across the vast and magnificent Grand Canyon of the Colorado in an epic tale of undying courage. This is a story of fearless river adventurers, brave and beautiful women and the early Mormon pioneers all of whose lives are interwoven with the Navaho, Hopi and the Havasupai...“The People of the Blue Green Water.” GRAND CANYON THUNDER is a never to be forgotten American saga written by multiple award-winning author Gary McCarthy.

Before man, there was a place of breathtaking beauty... a land forever wild, forever free. The Indians called it Ahwahnee. We know it as YOSEMITE. . .a timeless land of vast, unspoiled riches. . .where ancient tribes walked the sacred ground in peace and harmony. YOSEMITE. . .a paradise on earth that lured settlers like Joseph Walker to cross the mythical Sierra Nevadas and brave the perils of a great unexplored wilderness in search of fame and fortune. YOSEMITE. . .a coveted prize for those who would plunder its rich resources, it would take visionaries like John Muir and Theodore Roosevelt to protect this pristine land and preserve it as a sanctuary for generations of Americans to come. Painted on an authentic, larger-than-life canvas, filled with the men and women who made history, here is the epic story as spectacular in scope and stirringly beautiful as YOSEMITE itself.
