What animal burrows in hard ground where it is moist such as under snow or by sewer pipes?

The animal that burrows in hard ground where it is moist such as under snow or by sewer pipes is the mole. Moles are small, furry mammals that are well-adapted to digging. They have long, sharp claws and powerful muscles that allow them to dig through even hard ground. Moles also have small, beady eyes and poor eyesight, which helps them to navigate in the dark underground tunnels that they create. Moles typically live in solitary burrows, but they may come together to mate or to share food. They are found all over the world, and there are many different species of moles. Moles can be a nuisance to gardeners and farmers, as they can damage crops and lawns by digging up the ground. However, they also play an important role in the ecosystem by aerating the soil and helping to control insect populations.
