rendered the parameters involved in glass hydration understandable. However, the actual implementation of the physical processes described in the mathematical equations into a model replicating the natural environment is a complicated problem hard to solve (Stevenson 1998). THE DEVELOPMENT OF MODELS FOR THE UNDERSTANDING OF OBSIDIAN HYDRATION RATES In order to understand the obsidian hydration dating method, a model that can demonstrate the process of glass hydration under a certain range of environmental
Effects of The Pleistocene Epoch on Colorado INTRODUCTION Glaciers are an integral part of the world’s climate. In fact, as Richard Armstrong of the University of Colorado says, “Glaciers are key indicators in monitoring and detecting climate change” (Univ. of Colorado, Boulder, 2003, p. 1). Not only are they an important part of monitoring current climate, they can hold many keys to the past. Glaciers are in fact, “a source of paleoclimate data…” (Meier and Dyurgerov, 1980, p. 37). This
