A most excellent post, Mr. Birkeland. I especially enjoyed your last two paragraphs:
I don't "believe" in a specific origin of loess as the matter of its origin isn't a religious or personal matter dependent on faith or personal intuition. Instead, I accept the wind-blown origin of loess as an explanation for its origin based on data collected from field observations and laboratory analyses that show that the lateral distribution, stratigraphy, chemistry, and physical characteristics, i.e. grain-size distributions, of loess are all completely explainable with such an origin.
Accepting the wind-blown origin of loess as fact has nothing to do with personal belief, but rather the honest, scientific evaluation of hard, verifiable physical evidence and field observations along with credible published laboratory data.
