Claremore Mound, a natural feature in present-day Rogers County, Oklahoma.

The area on top of the mound, where the Osage built a village called Pasona about 1802, is about 25 acres (100,000 m2).

In June 1817, a band of Cherokee Indians and their allies, under Chief Spring Frog (Too-an-tuh), attacked Pasuga, an Osage Indian village at the foot of Claremore Mound, killing thirty-eight Osage, including their Chief Glahmo, and taking one hundred and four captives.

In revenge, the Osage attacked the Cherokee for the next twenty years, led by Wah-tianka, Glahmo's son.

Parts of the Cherokee reservation, established in the late 1830s in Indian Territory, lay about 2 miles (3.2 km) to the west.
