Why was the early West considered a "crossroads of culture"? - HELPP

B The California Gold Rush brought in people from all over the world, which resulted in cultural diffusion among the settlers there.

C California was known to accept many forms of religion and ethnicities, so people from different cultures migrated there to start new lives.
