How many Oregon Trail emigrants actually ended up settling in Oregon?
Answer: Around 20%
History - Only around 80,000 of the estimated 400,000 Oregon Trail emigrants actually ended their journey in Oregon’s Willamette Valley. Of the rest, the vast majority splintered off from the main route in either Wyoming or Idaho and took separate trails leading to California and Utah. The California Trail was eventually traveled by some 250,000 settlers, most of them prospectors seeking to strike it rich in the gold fields. The Utah route, meanwhile, shuttled roughly 70,000 Mormon pilgrims to the lands surrounding Salt Lake City.
