The Chippewas of Kettle and Stony Point will honour the return of the Thunderbird eggs at the First Nation's 55th annual Pow Wow this weekend.
The kettle rocks, known as Thunderbird eggs (Nimkii Waawaanag) in Anishinaabe communities, were rematriated to the Indigenous community last fall as part of Western University's commitment to reconciliation.
The spherical boulders are rare geological formations, made from calcite crystals more than 350 million years ago in shale beds that run through southwestern Ontario.
The cultural celebration is being held on the Pow Wow grounds at 9126 Lake Road on Saturday and Sunday.
There will be arts and crafts, traditional Indigenous cuisine, dancers in full regalia, drumming and singing.
Contests will be held for fancy, grass, jingle and traditional dances.
There will also be a baby contest on Sunday, with registration under the pavilion at 10 a.m.
Grand entry will start at noon each day, with an additional grand entry at 6 p.m. on Saturday.
Admission is $10, youth ages 6-13 are $5, children ages 5 and under and seniors are free.
