Crater Lake is a caldera lake in the western United States, located in south-central Oregon.
Crater Lake is also known for the "Old Man of the Lake". It is famous for its deep blue color and water clarity.
Two islands are in Crater Lake; Wizard Island formed from a cinder cone that erupted after Crater Lake began to fill with water, and the smaller Phantom Ship has seven different trees living on it.
There are no rivers flowing into or out of the lake. The lake is the deepest in the United States, and the seventh or ninth deepest in the world, depending on whether average or maximum depth is measured. The waters of Crater Lake are some of the purest because of the absence of pollutants.
Portland is the largest city in the U.S. state of Oregon. It is the 29th most populous city in the United States and the third most populous city in the Pacific Northwest region.
Portland has been recognized as one of the most environmentally conscious cities in the world, because of its public transportation networks and efficient land-use planning.
Portland has a climate marked by both warm, dry summers and wet, cool-to-chilly winter days. This climate is ideal for growing roses.
Portland has been known as the "City of Roses". Portland is often awarded "Greenest City in America" and "most green cities" designations. Popular Science awarded Portland the title of the Greenest City in America in 2008.
