River-Maker: Gabriel Moraga and the Birth of California’s Rivers

He didn’t conquer California. He named it—river by river, memory by memory.

In the early 1800s, Spanish lieutenant Gabriel Moraga rode deep into the wild, unmapped heart of California. What he discovered would shape the future of the West—but what he left behind was something far more enduring than conquest: names that still ripple across maps, city signs, and courtrooms today.

River-Maker is a breathtaking historical narrative that brings Moraga’s forgotten journey vividly to life—from the sweeping silence of the Central Valley to the tangled wetlands of the Delta, from encounters with native tribes to the quiet heartbreak of colonial duty.

Blending rich storytelling with true historical detail, this book reveals how one man—part soldier, part poet—gave voice to the land through ink and courage. In a world where rivers are dammed and memories buried, River-Maker asks the timeless question: Who gets to name a place, and what is lost when we forget them?

If you love books like Undaunted Courage, The Mapmaker’s Wife, or Empire of the Summer Moon, this is your next unforgettable read.
