The goal of the Ice Age Tonquin Trail is to present the impact of the Missoula Glacial Lake floods, a series of cataclysmic floods that formed the Columbia River Gorge and the Willamette Valley during the last Ice Age. Remains from the these floods can be seen along the existing and future trail include glacial erratics, scablands, kolk ponds, flood channels, and ripple marks. These floods carried the Willamette Meteorite embedded in an iceberg and left it deposited next to the Tualatin River in West Linn. It is the largest meteorite discovered in North America. Mastodon and Giant Sloth fossils from this time frame have been found in Tualatin.
The plan for the Ice Age Tonquin Trail plan to connect the Tualatin River National Wildlife Refuge with the Westside and Fanno Creek Trails as each crosses the Tualatin River. In additional, the trail will connect to the Willamette River passing through Wilsonville and Boones Ferry Park. The trail is in the early stages of development.
As a side note: Boones Ferry Park was the site of a ferry originally built by Alphonso Boone (grandson of Daniel Boone) around 1846. By the early 1900s, the State of Oregon as running the ferry. The ferry was shutdown in 1954 due to the completion of the Boone Bridge (used by I5). At time it was shutdown, the ferry was making 300 trips per day, carrying up to 12 autos at a time.
