Trail Highlights

Near Poplar, Montana (May 5, 1805)

• Captain Clark and George Drouillard encountered and killed a large brown bear.

Captain Lewis recorded:
📖 “He measured 8 feet 7 ½ inches from the nose to the extremity of the hind feet, 5 feet 10 ½ inches around the breast… his talons were 4 3/8 inches in length.”

• Milk River (Named May 8, 1805)
  The largest northern tributary of the Missouri River. Lewis described it as:
  📖 “…about the color of a cup of tea with a tablespoonful of milk… from the color of its water we called it Milk River.”

• Near Fort Peck, Montana (May 9, 1805)
  Buffalo herds were so dense that the men threw sticks and stones to clear their path. Lewis also wrote fondly of a dish called “boudin blanc” made from buffalo intestines.
