Note 147 — Chapter II

Eleventh Annual Report of the Peabody Museum, p. 226, Cambridge, 1878. Dr. Abbott concludes his interesting report by citing a letter from Mr. Thomas Belt, dated Grant, Colorado, June 29, 1878, in which the writer reports the discovery of “a small human skull in undisturbed loess, in a railway cutting about two miles from Denver, near the watershed between the South Platte and Clear Creek. All the plains are covered with a drift deposit of granitic and quartzose pebbles, overlaid by a sandy and calcareous loam closely resembling the diluvial clay and the loess of Europe.” The skull was found at a point three and a half feet from the surface.—Ibid., p. 257.
