On March 24, 1989, the Exxon Valdez ran aground off the coast of Alaska, spilling 11 million gallons of oil across 11,000 square miles of ocean. Jonah Winter recounts this incident in simple, straightforward text: thick, hot oil is pumped from deep underground into gigantic pipelines that cross miles of pristine wilderness to a port where it is transferred onto enormous ships. As one tanker glides past icebergs and sea creatures, it wrecks, causing crude oil to gush into the water, killing wildlife and spreading over miles of ocean and shoreline. Jeanette Winter's simple, uncluttered art depicts both the machinery of the oil industry and the natural beauty of the Alaskan arctic and northwest reaches of the Pacific, filled with snow, tundra, wildlife, mountains, and icy ocean vistas. Two wordless spreads pause the narrative and allow young readers to fully absorb the leak's impact. One depicts the initial breach with oil flowing all around unsuspecting sea creatures; the other offers an overhead ocean view, revealing the enormity of the disaster. Perhaps most moving, however, are the illustrations that show seabirds and otters covered in oily crude. Concluded with an author's note, suggested readings, and a final spread that reminds readers that some of the spill remains uncontained, this is an accessible and important contribution to environmental science.
