Mount Mazama is a dormant stratovolcano located in southern Oregon, USA. It is part of the Cascade Range and is best known for its caldera, which was formed during a massive eruption approximately 7,700 years ago. This eruption led to the collapse of the volcano, creating a large basin that eventually filled with water, forming Crater Lake. Crater Lake is the deepest lake in the United States and is renowned for its stunning blue color and clarity. The lake is surrounded by steep cliffs and is a popular destination for outdoor activities such as hiking, fishing, and photography, attracting visitors from around the world.
