"You did it!" Marvin said. "You found the hidden treasure at Mouse's Tank!"
The first installment of the series, this story is an exciting outdoor adventure set in a state park. Featuring the truck Marvin, his friend Vannigan, and their three doggie pals--Scout the Jack Russell and leader of the pack, Finn the Golden Retriever, and Finch the Brittany--this book teaches kids about the value of exploring nature and learning about their environment.
The group sets up camp and observes the impressive Arch Rock and the beautiful desert sunset. As the dogs venture off on their own to investigate Mouse's Tank, Vannigan encourages them to keep an eye out for some amazing things. Finally, the gang celebrates as the dogs discover the hidden treasure of the valley--petroglyphs! Author Rebecca Bodtke's engaging storytelling offers an accessible narrative that is sure to make any child look forward to their next trip outdoors.
