He would even remove them from history by removing them from pictures and destroying everything they ever had or wrote or built.</span>
A worker discovered it by accident.
There was a man named James W. Marshall who found gold on January 24, 1848, He saw something shiny in the stream. He had discovered gold unexpectedly while overseeing construction of a sawmill on the American River.

Have a great day
I also struggled with this question and I'm not 100% sure about my answer, but it's better than no answer. I used the little scale thing on the bottom right corner of the map. And I found out that by sea it was around 700 miles. And by land, I got around 350, but I rounded up to 400. Hopefully I was able to help... this stuff can be hard. I hate DBQ packets, but you gotta do your best.
Have a wonderful day and good luck in history :-)
