When do squirrels dig up their nuts?

I am seeing some squirrel digging up a lot of nuts right now. Do they find them by smell?

Early spring can be tough for squirrels. Winter food like apples, nuts, berries, and fungi are being consumed by many animals and new food isn't available yet. Fortunately many members of the squirrel family, hide food that they can recover on rainy days. Some food is cached for short periods, especially those made near the site of a sudden abundance of food which can be retrieved within hours or days for reburial in a more secure site. Others are more permanent and are not retrieved until months later.

Each Gray Squirrel is estimated to make several thousand caches each season. The squirrels have very accurate spatial memory for the locations of these caches, and use distant and nearby landmarks to retrieve them. Smell is used partly to uncover food caches, and also to find food in other squirrels' caches. However, scent can be unreliable when the ground is too dry or covered in snow.
