In Katy and the Big Snow by Virginia Lee Burton, the town of Geoppolis gets buried under feet and feet of snow after a huge storm. Thankfully Katy the red crawler tractor has her snow plow and can dig the city out! Follow Katy as she tunnels through snow to the police station, post office, railway station, telephone company, water department and more. Katy chug chug chugs along, clears the roads, and saves the day with her snowplow.
