The whole region is occupied by deposits from the Wisconsin glacial sheet. 16. _Bowers, Montgomery County._—Professor Donaldson Bodine of Wabash College, has informed the writer that about 1885 some remains of a mastodon were unearthed on the farm of Milton N. Waugh, near Bowers. The exact locality is said to be in section 12, township 20 north, range 3 west. This must be close to a stream named on the map Potato Creek. This lies north of the Bloomington morainic system or on its northern edge. The epoch of the animal is not earlier than Wisconsin. According to Jones and Orahood’s soil survey of this county (37th Ann. Rep. Geol. Surv. Indiana, p. 149), the glacial drift is almost everywhere overlain by loess, varying in thickness from a few inches to nearly 3 feet. This loess was deposited after the ice had retired from that region. 17. _Indianapolis, Marion County._—In the State Museum at Indianapolis there is a lower right last molar labeled as having been found in Indianapolis, at Pennsylvania and Thirtieth streets, by workmen who were digging a sewer. This was probably in outwash materials brought down by Fall Creek from the northeast during the withdrawal of the Wisconsin ice from the Bloomington moraine to the one which passes through Union City and Muncie, called the Union City moraine. 18. _Anderson, Madison County._—In the Indianapolis Star of July 30, 1911, is an account of the finding of jawbones, with teeth, of a mastodon. The account was accompanied by reproductions of photographs, which make the identification certain. The remains were found on the farm of Louis Webb, but the exact location was not indicated. The animal certainly lived after the culmination of the Wisconsin stage. Leverett (Monogr. U. S. Geol. Surv. LIII, p. 99) states that in parts of central Indiana the Wisconsin drift may be relatively thin, as little as from 15 to 20 feet. In western Tipton and southern Clinton Counties a buried soil about 20 feet below the surface seems to represent the land surface previous to the Wisconsin invasion. In southern Madison County a black mucky soil, carrying pieces of wood large enough to be called logs, underlies the till at from 15 to 40 feet. Such a soil would be the product of the interval between the Illinoian glacial stage and the Wisconsin, probably either Sangamon or Peorian. In such deposits there might be found vertebrate remains, possibly even of horses.
