Almo is an unincorporated town in the Upper Raft River Valley in Cassia County, Idaho, United States.

[1] Almo is just over 2 miles (3.2 km) east away from the City of Rocks National Reserve, a 14,300-acre (58 km2) area with granite columns as much as 600 feet (180 m) high.

Many pioneers followed the Oregon Trail west in the middle of the 19th century, and passed by the future site of Almo.

However, the earliest written record of this event is from 1927, and the total absence of information about either the slaughtered pioneers or the five survivors has led the Idaho State Historical Society to recommend the removal of the marker,[5][6] which the town has refused to do.

Almo at the turn of the century boasted a store, a post office, a school, a brass band, a theatrical group, three saloons, and a welfare society.
