Prarie dog and the Lost Wheel

Prairie dogs are named for their habitat and warning call, which sounds similar to a dog’s bark.

According to the Online Etymology Dictionary, the name is attested from at least 1774.The 1804 journals of the Lewis and Clark Expedition note that in September 1804, they “discovered a Village of an animal the French Call the Prairie Dog”

The Prairie dogs tunnel systems help channel rainwater into the water table to prevent runoff and erosion, and can also serve to change the composition of the soil in a region by reversing soil compaction that can be a result of cattle grazing.

The tunnels usually have several chambers. Tunnels can descend vertically as much as 5 metres (16 ft), and can extend laterally as much as 30 metres (98 ft). Prairie dogs line their burrows with grass to insulate them,

and the earth excavated from the burrow is piled up in mounds around the burrow’s entrance. The prairie dogs use these carefully maintained mounds as observation posts.

In the city of Boulder,CO, smoking is prohibited within 20 miles of a prairie dog.
