Description: 
During the austral summer 1967-1968, a soils study was made of a sequence of moraines around the MEserve Glacier produced over the last two million years by an Alpine glacier. Chemical and physical criteria obtained from the soils, when taken together, established a set of reliable indices of relative ages for the moraines. The same information related to the fine ages for the moraines allows the use of the criteria in areas where neither relative nor finite ages are available. It also provides a basis on which to judge soil genesis. The physical parameters investigated included color, texture, presence or absence and amount of free salts, degree of salt induration, and the amount and appearance of granules and cobbles up to 30cm size (skeleton). Comparison of selected chemical parameters indicated that maximums of SO4, exchangeable sodium and electrical conductivity profiles coincide with the position of the clay peak and the salt-indurated layer. This layer is considered the most significant characteristics of the soils in the Meserve Glacier areas.
