Answer:
Before the gold rush, the west was wild, and there were fewer individuals around. The large urban communities in California were shires with a couple of hundred natives. While the large harbors got perhaps 2 - 3 ships, every week before the surge, there were dozens of boats a day once gold was found.
The railways would turn into the best drivers of westbound development since they brought individuals west and permitted the things they created to be sent east.
The correct answer to this open question is the following.
The California gold rush transformed the west in the American imagination in that the arrival of so many people that dreamt to find god a became rich, made possible the transformation of a region that before the gold rush, it was isolated with very few people and houses in that territory. But During and after the gold rush, the place changed completely because thousands of people settle in and formed new communities. Without a doubt, the massive migration changed the way that the place looked.
