Introduction,rock, soils, vegetation, surface waters, and their communities are all shaped by climate, natural disturbances such as fire, and interaction with each other. Each component, whether animate or inanimate, is part of the ecosystem. Each unit contributes to the cycling, transforming, or holding of ener

In the south it merges with a complex highland overlooking South Park (Ives 1980). The Front Range is a Laramide structure with a core of crystalline rocks made of predominan

An understanding of the hydrology of these souce regions is important to understanding regional water supplies. It is also vital to understanding the biogeochemical responses of alpine and sub

Central to the question of acid deposition effects, we found no evidence that either current or historic precipitation contains enough strong acid anions

Recently disturbed vegetation may exhibit increased rates of nitrification and consequent acidification of stream water (Bormann and Likens 1979), while areas wit

On an areal basis, 82% of LVWS is composed of rock outcrop and talus slopes derived from glacial activities or frequent debris flows and avalanches that characterize this youthful and steep terrain. The two dominant rock units found within LVWS are a biotite gneiss and the Silv
