Crater Lake, located in southern Oregon, is a breathtaking natural wonder that offers visitors a variety of outdoor recreation opportunities. The lake was formed over 7,000 years ago after a volcanic eruption left a caldera that filled with rain and snowmelt. The climate in the area is generally cold and snowy, with winter temperatures often dropping below freezing. The lake's hydrology is attributed to its high elevation and deep, clear waters, which are fed by snowmelt and precipitation. The lake's unique geology also contributes to its vibrant blue color. Visitors can enjoy hiking, skiing, snowshoeing, and camping in the surrounding area, and there are several scenic viewpoints and trails that offer stunning views of the lake and its surroundings.
