tired

I am so tired because I worked last weekend..
I did not study american history in detail so when I watched TV show, it said really interesting.
it said that with the dream of finding vast stores of gold in the north American continent, the Spanish conquistadors launched expeditions from the west indies and Mexico in the 16 th century. to coronado, the explorer, the southwestern derserts were an arid hell, eventually reached the Grand Canyon at the height of summer's heat, but thirsty as they were, they could find no way to reach the cororado river, shimmering 1.6 kilometers below.
Is this famous story in here? and it is pretty sound stupid.
