Island Origins: Trappers, Traders & Settlers by J. D. Cleaver is a 1986 regional history, published by the Oregon Historical Society Press as the inaugural volume of the Sauvie Island Heritage Series. The book meticulously examines the early history and geological formation of this significant river island—located at the confluence of the Willamette and Columbia rivers near Portland—during the initial stages of Euro-American contact and settlement from 1792 to 1865. Cleaver chronicles the era of early maritime explorers, the establishment of the region's lucrative fur trade, and the arrival of the first pioneer homesteaders who began transforming the landscape. Ultimately, it serves as a foundational and highly focused resource for understanding the complex ecological and colonial forces that shaped one of Oregon's most historically vital trading and agricultural hubs.
