On this day in Lewis & Clark history...

Clark kills a pronghorn and Shields kills a white-tailed jackrabbit. Lewis scientifically describes both in his natural history notes. Clark searches unsuccessfully for an old volcano reported to be in this part of present South Dakota.

From the journals...

I Killed a Buck Goat of this Countrey, about the hight of the Grown Deer, its body Shorter, the Horns which is not very hard and forks 2/3 up    one prong Short the other round & Sharp arched
he is more like the Antilope or Gazella of Africa than any other Species of Goat.
