A mole can dig a tunnel 300 feet long in just one night!

In dirt soil a mole can dig a tunnel 300 feet long in just one night. At tunnel entrances, the dirt is kicked out by the hind feet into mole hills. In long, deep tunnels the dirt is compacted into the walls by the mole's body. In shorter tunnels the mole can turn around and push some of the loose soil out with its nose. Also there is a popular belief that the mole is blind which a misconception. A mole has eyes but they are very small and thus protect them from dirt and infection. Their eyesight is poor because we know they can’t detect color, but a mole's eyesight is sensitive to movement and light which helps it when emerging from beneath ground. Changes such as these in a mole's environment will also tell it certain things about where it is in relation to its burrow.
