Curiosities: How do squirrels find the food they squirrel away come spring?

Mainly by nose, said Scott Craven, emeritus professor of wildlife ecology at UW-Madison. “The consensus among scientists is that the gray squirrel uses its sense of smell, even through deep snow.”
And, thankfully, the squirrels don’t find every nut or seed that’s buried, which is why we have oak trees from coast to coast.
