The next appears to be the first steam up for the day of old number 40 of the Knott's Railroad. I like how everyone is admiring the engine and the nice detailing on the engine.
The third shows the old volcano. The prospector in the back better move before the eruption hits him with lava and steaming water.
And the last shows the old Blacksmith shop. It definitely looks like it was a calmer, gentler time when these images were taken.
