Beautifully Barren
Walking on tundra at Sentry Island, a place well-utilized by Inuit "summer campers" since prehistory.
The entire island is a long, low sandy esker (glacier river bed) atop of glacial tills reworked by the marine beaches forming beside Hudson Bay. An esker is an in-glacier river formed during the melt-down of 3 km thick continental glacier ice sheet. The eskers hereabouts, like the glacier, flowed from west to east into Hudson Bay. The photo faces west or "up-stream" and "up-ice". The horizon is the mainland.
The land hereabouts is still rising from the release of the weight of ice sheet melted 8,000 to 10,000 years ago.
