At its maximum, the glacial Lake Agassiz was larger in surface area than all the present-day Great Lakes combined. Glacial Lake Agassiz began draining roughly 8,500 years ago, leaving a scattering of relic lakes and distinctive landforms. The story of this vast lake continues to unfold at Agassiz Dunes SNA.
The site's hallmark feature is its dunefield, comprised of sediments that originally accumulated here as a delta where the Sand River entered Lake Agassiz. Sculpted by wind over centuries, the landscape remains a work in progress, with fossil dunes, younger secondary dunes and modern blowouts.
This site has no maintained trails or other recreational facilities.
