His tale of riches, repeated numerous times over the years, goes something like this: While on a beaver trapping expedition in Arizona, Smith and a companion reached the Colorado River near what is now Yuma Arizona and from there proceeded across California's desolate and uninhabited southern desert.
They traveled on horse back with bales of hides packed on mules that trailed behind.
They hoped to find a market for beaver pelts in Los Angeles.
All 1827-28 expeditions by Americans were forced by the authorities to confine their trapping to
areas outside of what was then Mexico. During this season, Smith partnered with a group
trapping the area north of the Platte River in Colorado.
It was on this trip that Smith lost his foot and the lower part of his leg. As he tells it,
"I was ambushed by an Indian and shot in the leg".
After the leg was successfully amputated, the party waited around and when Smith refused to die,
they slung him between two horses and continued on to the north.
Bad weather forced them to take winter quarters near the Colorado-Wyoming border.
Smith emerged in the spring with a wooden stump that he had whittled out of an oak sapling and a new name.
