Why they migrated
Why the 49ers migrated was because citizens of California spread the word out through the east and people from the east migrated the west to California because they wanted to travel to the Yukon to find gold because they really wanted to find something that wouldn't think they could ever find. Some of the miners ended up finding gold and came back to there families wealthy and some came back penniless because it was expensive to go up to the Yukon.
