Surrounded in mystery and misinformation, Steve and Kathie Libert reveal the location of the elusive Huron Islands where Le Griffon met its fate. It is here that an exciting discovery of what appears to be a colonial-aged shipwreck was found. This location is precisely where their research places her final moments. It was among these islands where in 1679 Robert La Salle’s flagship Le Griffon disappeared. Cursed by the local Indian tribes, her disappearance became an unsolved mystery for La Salle who searched for her whereabouts to no avail. Ironically, if the ship proves to be Le Griffon, she lays quietly under tribal waters adding to the mystique of her story. Utilizing primary source documents, the Liberts take you on a historical journey of exploration and discovery in solving the first Great Lakes maritime mystery, Le Griffon and her final resting place. https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1616694452653-WLD6VY539717A9INVMNA/Kathie%2B%2526%2BSteve.jpg Home Kathie and Steve Libert https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614680696133-GM5QSXVWUNWSJPUK2EXR/about_1_L.jpg Home “Building Le Griffon (Hennepin, 1704)” https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614680857185-QVZ3606ERSFF7Z1J7OY0/about_2_L.jpg Home Sieur de La Salle https://www.greatlakesexploration.com/the-team daily 0.75 2021-02-22 https://www.greatlakesexploration.com/press-release daily 0.75 2021-02-22 https://www.greatlakesexploration.com/about daily 0.75 2021-05-08 https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614446879751-422XKAI678B1O5X0E94S/Screen+Shot+2021-02-27+at+6.27.33+PM.png About https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1619449765919-3JPG8BPBGNUJPVSG89WN/LaSalle-Griffon+Logo-Blk%26White+copy.jpg About https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614784829491-03MC8HVRQKP6LL7IKFQ4/Screen+Shot+2021-03-03+at+4.19.12+PM.png About https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614448140964-9OJZPB8218OD88X1WRU0/Screen+Shot+2021-02-27+at+6.45.39+PM.png About https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614446717442-1CH9K55EHV8E46PG00RX/Screen+Shot+2021-02-27+at+6.24.20+PM.png About Vance Skowronski, Jim Kucharsky, Tom Kucharsky and Steve Libert https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614447627289-F0PD4LH7JTF308H4Y73P/Screen+Shot+2021-02-27+at+6.29.36+PM.png About click on photo for more information about Allen Pertner https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614447174023-4LWQMF2SH0SHZUJ72SJA/Screen+Shot+2021-02-27+at+6.29.17+PM.png About Click on photo for more information on Steve Libert https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1614784787693-NYXMZZF470LPKQSTGNIX/Screen+Shot+2021-03-03+at+4.19.20+PM.png About https://www.greatlakesexploration.com/about-us-gallery daily 0.75 2021-03-03 https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/f1134b8b-3c62-4d64-9876-eba66d2a6102/presspic1__L.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/21a39420-44fa-4c18-a6d4-9d4920c71fc8/griffon10.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/ef33fd35-d990-4723-abd5-3c2c4f4e93ef/griffon06.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/ee738024-3c4f-4ba6-842d-008a52663ddc/griffon02.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/b1c217ac-173c-458e-8eec-12d35a9331df/Avec+Steve+Libert+156.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/7705ab32-210f-4975-9884-7cf99d4aeb7e/expedition_4_L.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/24b67853-b1d3-4ab0-9150-668d162f8151/griffon14.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1dece463-a78b-4d51-a886-0b4099f908e5/expedition_3_L.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/f0e2d039-c792-4532-b56f-0f7cd631b037/Libert3_L.jpg Photo Gallery https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/f93aa941-3255-469a-8c56-643ca5522865/presspic2_L.jpg Photo Gallery https://www.greatlakesexploration.com/steve-libert daily 0.75 2021-05-08 https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1615322850411-FXH79OM3CRHN9IQGE9H3/2.jpg Steve Libert https://www.greatlakesexploration.com/allen-pertner daily 0.75 2021-03-13 https://images.squarespace-cdn.com/content/v1/6033abc067a0aa2fe9cb4c3a/1615322625853-90KQVN3RKM08R57XBMNX/Al%2Bwith%2BScuba%2BGear.jpg Allen Pertner https://www.greatlakesexploration.com/take-action daily 0.75 2025-05-12
