Be careful not to confuse mail drops with litter bins, though - they can sometimes be similar in design. Mail drops are dark blue and have the Postal Service logo on them. The slot has a counterweighted flap which you open in order to deposit your mail. Stamps are best obtained in post offices. Although they are the same price at other sources, the post office will be able to look up the correct cost of sending mail abroad.
Many houses also have simple plastic boxes outside for newspapers to be delivered.
Muir, John John Muir was one of the main founders of the US National Park Service. Muir Woods National Monument near San Francisco in California was named in his honour. In 1869 John Wesley Powell was the leader of the first expedition to navigate the Colorado River through the Grand Canyon . The expedition used wooden boats. The name comes from the thunderbird, or phoenix, which is a spirit sacred to many Native American tribes.
