it opened up the pacific coast to colonialism - if that is a good measure!?!?

it opened a new el dorado for the europeans - the whites who destroyed local culture, religion, custom etc and imposed their white, anglo-saxon, judaeo-christian values on these original inhabitants of america before it was called america. they made them alcoholics, infested them with small pox and other kinds of diseases to wipe them off.
