Golden Gate: Building the Mighty Bridge by Elizabeth Partridge, illustrated by Ellen Heck (Chronicle Books, 60 pages, grades 2-5). The two children of a lighthouse keeper observe the creation of the Golden Gate Bridge from their house. Told in second person narration (“You leap out of bed–how did you forget? Today’s the day work begins on the Golden Gate Bridge”), the text includes plenty of construction details and emphasizes the seemingly impossible nature of the project. As the kids grow older, the foreman gets to know them and sometimes includes them in some aspects of construction, like the day they get to ride the elevator to a height of 700 feet above the water. Finally, on May 27, 1937, the Golden Gate Bridge is open to the public, and crowds of people, including the two children, walk across the bridge, where “the word impossible seems like nothing at all.” Includes an afterword with additional information.

Great Lakes: Our Freshwater Treasure by Barb Rosenstock, illustrated by Jamey Christoph (Knopf Books for Young Readers, 40 pages, grades 2-5). Beginning with the history of the five Great Lakes, formed by the melting of a huge glacier that covered more than half of North America, the narrative shifts to the present importance of the lakes. Not only are they home to many species of plants and animals, but they contain almost all of the surface freshwater in North America. Although they are essential in supporting humans, we’ve done our best to poison and pollute them. In recent years, work has been done to protect them, and readers are invited to investigate how they can help preserve these national treasures. Includes messages from the author and Kathleen Smith, an indigenous woman from the Great Lakes Indian Fish and Wildlife Commission, information about the Center for Great Lakes Literacy, and a list of sources.

Both of these books are chock full of fascinating information, well supplemented by beautiful, detailed illustrations, that will help readers better understand two famous American landmarks. Although they are both picture books, each one contains quite a bit of text and somewhat technical information, making them better choices for older elementary and middle school readers.
