Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.Process of Metamorphism:The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact rocks. New minerals are created either by rearrangement of mineral components or by reactions with fluids that enter the rocks. Pressure or temperature can even change previously metamorphosed rocks into new types. Metamorphic rocks are often squished, smeared out, and folded. Despite these uncomfortable conditions, metamorphic rocks do not get hot enough to melt, or they would ...

Drought can take different forms across the Intermountain West. This region includes many different climatic, geographic, economic, and social conditions. These include deserts and forests, fertile valleys and alpine peaks, densely populated cities, and some of the most remote landscapes in America. Drought onset may occur quickly and last a season, or begin gradually and last decades. The Rocky Mountain regions rely on winter snowpack to sustain cities, towns, agriculture and recreation. In the Southwest, the summer monsoons help people, and livestock, get through the hot summer months. In addition to (and because of) the highly variable precipitation, all five states in the Intermountain West also depend on the over-allocated Colorado River for a consistent water supply. The Intermountain West DEWS helps foster interstate coordination to cope with current and future droughts and growing water demands and supports increased communication and collaboration between scientific, water, and land management communities.Primary contact: Meredith Muth, Acting Regional Drought Information Coordinator
