Herschel Island in the southern Beaufort Sea is a push moraine at the northwestern‐most limit of the Laurentide Ice Sheet. Stable water isotope (δ18O, δD) and hydrochemical studies were applied to two tabular massive ground ice bodies to unravel their genetic origin. Buried glacier ice or basal rege...
