Any #glacial geologists/geomorphologists wish they could see inside an #esker? There's a place in north #Norfolk where you can.
Lidar image and three photos here. Uppermost preserved layer contains densely-packed, well-rounded flint cobbles, indicating powerful water flow.
N.B. car keys included in close-up photo for scale.

Any ideas what spawned this feature?

(straight ditches are anthrostuff)

The center of this marshland feature is almost perfectly round. It’s connected to Back River in Weymouth, Massachusetts. Back River’s tidal range is up to ~4 meters. The marsh is next to Great Esker, one of the tallest in North America, ~30 meters. Smaller, similar features are offshore.

Located at 42.24N 70.93W

Walking on eskers is just always nice. Thank you, Ice Age, thank you winter. #walking #esker #nature

Esker walk just before sunset (currently after 3 pm hereabouts in Finland). #esker #nature #walking #winter
