火山湖就是在火山口的湖泊,火山湖有比一般湖泊的独特魅力。Crater Lake National Park,位于美国俄勒冈州,公园建于1902年。这个位于海拔8000多英尺高的湖,是7000多年前,由一座叫做Mount Mazama的古老火山喷发形成的。火山爆发后,火山的顶端坍塌,形成了一个火山口。由于岩浆的流动封住了火山口底部,使得火山口逐渐聚积了常年的雨雪,最终因此形成近2000英尺深,拥有4.6万亿加仑水资源的火山湖,它是美国第一深湖, Volcanic lakes are the crater lakes, volcanic lakes than the average lake unique charm. Crater Lake National Park, located in the United States, Oregon, the park was built in 1902. This lake, located at over 8,000 feet above sea level, was erupted 7,000 years ago by an ancient volcano called Mount Mazama. After the volcano erupted, the top of the volcano collapsed, forming a crater. As the flow of magma sealed the bottom of the crater, crater gradually accumulate perennial snow and rain, and ultimately the formation of nearly 2,000 feet deep, with 4.6 trillion gallons of water resources, volcanic lakes, it is the first deep lake in the United States,
