The Lake Ridge Island Mounds are a group of small hills in Logan County, Ohio, United States that have been thought to be Native American mounds. Located in an area of about 5 acres (2.0 ha) at the northern end on Lake Ridge Island in Indian Lake, the mounds are near the village of Russells Point in the southeastern corner of Stokes Township. State Route 368 passes a short distance to the east of the mounds, even weaving at one point to avoid them. The four mounds on the island are small, not reaching a height greater than 3 feet (0.91 m) or a diameter greater than 40 feet (12 m); they are small enough that they appear to be natural knolls. A report produced in the 1970s observed that the mounds were in "excellent" condition at the time, never having been disturbed by artifact seekers.
