drumlin - a whale-shaped hill

it's in the background and nothing to do with the furrows in foreground?

These are sand ripples, (I don't know if there's another name for them), unrelated to drumlins.

The ripples are shaped by wind, found anywhere there's lots of sand - not always by water.

Drumlins are found where once were glaciers.
Only coincidentally by a sandy place &/or a body of water.

The AWAD pic was a bit confusing.

(It scares me that glaciers are melting so quickly now.)

Hm-yes, hum, the grumlin is in the background, the fake drumlins are in the foreground.
