sand dune

As this joyless impossibility flitted across my mind, I rounded a bleak sand-dune.

The shooting he had heard some time previous to his appearance at the base of the big sand dune had not been done by Indians.

In a moment, under the lee of a sand dune, they came upon two muffled figures holding two camels, which were lying down.

After whispering together a moment one of the little gnomes ran up the beach and over a sand dune.

The weather, of course, prevented them from walking up the Beach to their sand-dune.
