How did the klondike gold rush differ from the california gold rush that took place half a century earlier?

You can go Klondike only by the Yukon River, you can choose upstream from its delta, downstream from its head, or from somewhere in the middle through its tributaries. While it’s difficult to get to California; forty-niners faced hardship and often death on the way. At first, most Argonauts, as they were also known, travelled by sea. In the East Coast, they sail around the tip of South America would take five to eight months and cover some 33,000 kilometres and another way was to sail to the Atlantic side of the Isthmus of Panama, take canoes and mules for a week through the jungle, and then on the Pacific side, wait for a ship sailing for San Francisco. There was also a way across Mexico it begins at Veracruz.
