The Ice Age and its ending have been dated based on uniformitarian thinking with 14C, dendrochronology, varves and many tens of other dating methods. These dating methods have been correlated to each other, and basically have been fitted to the uniformitarian interpretation of the geological column.
The methods, which are stated to be more important, have been more carefully studied. These methods are sometimes even labeled “absolute,” and are the main methods for correlation and especially dating of the last stages of the Ice Age. Fieldwork on Swedish laminated clays called (yearly) varves show climbing ripples and water escape structures, hence showing that the “varves” cannot be yearly but must instead sometimes even have been catastrophically deposited. Also, the “absolute” correlation of 14C dates and dendrochronology has been shown to be faulty, and fits a short biblical chronology very well.
Glacigenic erosional and depositional landforms, for example, extent and stratigraphy of tills, moraine forms, depth of glacial erosion, and glaciofluvial sediments, all indicate one single short Ice Age
