OREGON CITY - View this location on map Entering California over the Applegate and Lassen Trails, a party of Oregonians arrived here in autumn of 1848 to establish Oregon City. Little more than a year later their captain, Peter H. Burnett, became the first civil Governor of California. For a time, Oregon City prospered as a gold mining and supply center - then it declined into virtual oblivion. 100 Diggins Dr , , California Historical
