Calla Lilies near Rodeo Beach in the Marin Headlands, a hilly peninsula at the southernmost end of Marin County, California, United States, located just north of San Francisco across the Golden Gate Bridge, which connects the two counties and peninsulas. The Marin Headlands were home to the Native American Coastal Miwok tribe, who moved between the bay side of the peninsula and the ocean side seasonally, for thousands of years. The entire area is part of the Golden Gate National Recreation Area. The Headlands are famous for their views of the Bay Area, especially of the Golden Gate Bridge. In the waters surrounding the Headlands, harbor seals can be found year-round, gray whales can be seen in the spring and fall, and seabirds such as common murres and surf scoters swim within sight of shore.
One of the most recognized landmarks in Zion National Park, Court of the Patriarchs reach into the Utah sky. These three photogenic peaks bear the biblical names of Abraham, Isaac, and Jacob. Towering above Birch Creek Canyon almost 2000 feet, the Court of the Patriarchs represents nearly a full layer of Navajo Sandstone. This exposed sandstone is one of nine Zion rock layers that together span 150 million years of sediment deposits. The Patriarch cliffs represent one of the thickest layers of sediment, making up some of the tallest cliffs in the world. Occasional flash floods in the Virgin River increase water volume by 100 times and bring down tons of loose rock and sand, scouring out new side canyons and re-channeling the river. Here in Zion Canyon this magnificent scenery is always experiencing change, but its subtleties are seldom recognized in such an immense canyon.
