People arrived in California using ships and horses.
Step-by-step explanation:
Hello. You did not present the maps to which the question refers, but through a quick search on the internet, we can find information that during the Gold Rush people arrived in California using ships and horses.
The gold rush took place between 1848 and 1853, when an exorbitant number of foreigners and Americans living in other states migrated to California to try to find gold, which apparently existed in the region. It is estimated that at that time California received about three hundred thousand people, where the majority of Americans and Mexicans arrived using horses, but a large number of foreigners arrived in California using ships.
