We walk back in time passing through Tunnel Number Six (infamous as the most difficult-to-complete section of the entire Transcontinental Railroad) – to the craggy gap that the emigrant Stevens and Donner parties struggled through with their wagons – down to some of the oldest petroglyphs found in the Sierra. Along the way we will share readings describing the Chinese rail worker experience, harrowing stories from the emigrant pioneers, and tales of initiation from California’s Native American tribes. Students will do a creative writing assignment describing a “day in the life” from one of the periods studied.
