Often, we see geniuses and other intellectually gifted people in media portrayed as weirdos, who have certain eccentricities that make them stand out in the minds of other people. They may be awkward but they do what they want without heeding how others may say about them.
In the 1840s, there lived one such man named Josiah Gregg and this is the story of his final adventure:
In November 1849, eight men set out from their “gold diggings” on the North Fork Trinity River in Northern California into a range of forested mountains that had never been mapped. Their leader was Josiah Gregg, a math whiz, self-taught navigator, medical doctor, and obsessive botanist.
