The town began with a store and gas station during the construction of US 212 in the 1930s. In the 21st century, Hammond has consisted only of an active post office and a rancher's home. Three other buildings along the highway are abandoned and deteriorated beyond use. Hammond is located in the southeast corner of the state, near the Montana-
Wyoming border between the unincorporated communities of
Boyes and
Alzada in Carter County. Hammond is southwest of the Carter County seat,
Ekalaka. The area around Hammond is mostly ranchland. ==Climate==
