Authored collaboratively by the Wasco County Historical Society and the Clackamas County Historical Society, Barlow Road chronicles the construction and historical legacy of the final, grueling overland leg of the historic Oregon Trail. The book traces how Sam Barlow’s 1845 toll road carved a hazardous wagon route around the treacherous southern flank of Mount Hood, offering exhausted pioneers a perilous alternative to navigating the dangerous rapids of the Columbia River. Through archival maps, journals, and photographs, the text details the monumental physical labor required to hack a wagon track through dense old-growth forests and volcanic terrain. A keen insight drawn from the work is how the creation of the Barlow Road transformed a humanitarian struggle into a capitalist enterprise; by privatizing the final mountain obstacle of the migration route, the toll road proved that the westward movement was driven as much by entrepreneurial toll-gate economics as it was by Manifest Destiny.
