Blackbird Hill is the burial site of several Omaha chiefs, including Chief Blackbird who died in 1800 during a smallpox outbreak. In 1804, the Lewis and Clark expedition visited the site to pay their respects to the chiefs.

The hill is a 300-foot-high promontory on the west side of the Missouri River in present-day Nebraska. On August 11, 1804, Lewis, Clark and ten other men climbed the hill to visit the grave of Omaha Chief Blackbird, whose ruthlessness had gained him notoriety among other tribes and traders from St. Louis. Clark wrote, “We landed at the foot of the hill on which Black Bird The late King of the mahar who died 4 years ago & 400 of his nation with the small pox was buried and went up and fixed a white flag bound with blue white & read on the grave which was about 12 foot base & circueller, on the top of a Penical about 300 foot above the water of the river, from the top of this hill may be Seen the bends or meanderings of the river for 60 or 70 miles round.”

Blackbird Hill remained a distinctive landmark for river travelers throughout the 19th century. It was paint­ed by George Catlin in 1832 and Karl Bodmer in 1833. According to traditional Omaha tribal accounts, Chief Big Elk was also buried at this site. In a downslope gorge, natural sandstone bedrock exposures display a collection of petroglyphs that depict human, animal, and supernatural figures. While tribal or chrono­logical affiliation of the petroglyphs is unknown, one resembling a human on horseback is likely to be post-1700 CE. Located within the Omaha Reservation, Blackbird Hill is privately owned but publicly viewable from adjacent roadways.

Blackbird Hill is a High Potential Historic Site on the Lewis and Clark National Historic Trail.
