It's June, and Aldo's mom has decided to drag him—together with his classmate Marvin and Marvin's mom—on a camping trip. After a stop at majestic Mesa Verde National Park, the foursome strap on their backpacks and head into the Utah wilderness in search of a rare spotted owl and other natural wonders. Will Aldo muster the self-sufficiency to survive when disaster strikes? This thirteenth installment in an A-to-Z alphabet series also includes a glossary of fun and challenging "M" words, such as malarkey, moonstruck, and mumbo-jumbo.
