"Aeolian activity of this kind has been described from Montana, Patagonia,
the Sudan, and elsewhere, and may still be seen operating on a feebler
scale in North China to-day. The imported sediment which fell at Peking
during one night of a heavy dustfall in March 1927 was estimated at 110
tons per square mile. Microscopic analysis showed it to be
indistinguishable from typical loess of the Malan type." ~ George Barbour,
"Recent Observations on the Loess of North China," Geogr. Jour.,
86(1935):1:54-56, p. 55, in Ian J. Smalley, Loess (Stroudsburg, Dowden
Hutchinson & Ross, Inc., 1975), p. 56
It seems that the 4th dimension isn't really needed to produce loess.
