1902 Map of Corona

Rail transport is the lifeblood of the era, with numerous spurs like the Southern Pacific R.R. Newport Beach Branch and the California Southern R.R. connecting small shipping points such as El Modena Sta. and Marlboro. To the east, the Santiago National Forest covers the steep canyons of the Santa Ana Mountains, where a lonely Coal Mine sits in Fremont Canyon. The coastal region is defined by the wetlands of Newport Bay and the early layout of settlements like Bolsa and Talbert.
