The Mammoth and the Flood - a review of Howorth's book. The drumlins in this photo occur in the vicinity of Snare Lake, Saskatchewan, Canada. The width of the area shown is about four miles. Sir James Hall of Edinburgh proposed a diluvial explanation of drumlins in 1814. The diluvial explanation of drumlins seems to be long overdue for a comeback.
Conventional geology says patterns of stratification in sandstones are invariably sedimentary.
An alternative explanation for patterns of cross stratification in sandstone is that these patterns may have formed due to a crystallization process, that produced sand in successive layers. According to this theory, the material which crystallized, forming sand or sandstones, was probably hydrous amorphous silica. Hematite coatings on quartz sand grains may have formed by exsolution. This process, of course, is not observed occurring anywhere in nature today, but may have operated in the past, in former conditions, as pressure was released due to erosion of overburden caused by rapid currents generated by differential crustal uplifts as the flood waters retreated from the land. The currents flowed away from centers of uplift.
