Join Winding Waters River Expeditions
and the Oregon Paleo Lands Institute for
this unique Journey through the “suture
zone”. This 5 day expedition down the
free-flowing Salmon River of Idaho will
begin near Whitebird. This section of
the Salmon River flows through what
geologists call the “suture zone”.
Approximately 300 million years ago,
this region would have been beach-front
property, defining the western shore of
North America.
Off the coast, a chain of volcanic
islands was forming, creating an island
arc similar to Japan. Roughly 250
million years ago, as Pangaea was
breaking up and the Atlantic Ocean was
opening, the North American plate began
moving to the west and over-riding the
Pacific plate. As the Pacific plate
subducted under the North American
plate, the island arc was accreted onto
the North American continent, like
butter off of a butter-knife, creating
the first real-estate in Oregon and
Washington. This meeting point of North
America and the island arc is the
“suture zone”.
Come and explore the geologic story
of this dynamic zone. Rediscover some of
the clues that led geologists to develop
this “suture zone” theory. Float through
many beautiful deep canyons and view
some of the basement rock of the North
American continent, exposed by the
powerful Salmon River. In addition to
learning about the geology, we will run
exhilarating whitewater, eat fabulous
meals, visit cultural sites, camp on
white sandy beaches, and create memories
to last a lifetime.
