Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Muna 1850, sango remuti mutsvuku wakakura kare rakanga rakafukidza maeka anopfuura 2.000.000 (8,100 km2) emhenderekedzo yegungwa yeCalifornia. Rutivi rwokuchamhembe rwenharaunda iyoyo, rwaimbogarwa navaNative American, rwakakwezva vatemi vemiti vazhinji uye vamwe vakava vanochera ndarama apo kuwanda kwegoridhe kuduku kwakavaunza kunharaunda yacho. Vachikundikana mukuedza kuriwana rakapfuma nendarama, ava varume vakatendeukira kukucheka miti mikuru nokuda kwokuvandudzwa kunobudirira muSan Francisco nedzimwe nzvimbo dziri paWest Coast. Pashure pamakumi amakore akawanda okucheka miti pasina ganhuriro, nhamburiko dzakakomba dzokuchengetedza dzakavamba.
