Some mounds were developed with separate levels (or terraces) and aprons, such as Emerald Mound, which is one large terrace with two smaller mounds on its summit; or Monks Mound, which has four separate levels and stands close to 100 feet (30 m) in height. Monks Mound had at least ten separate periods of mound construction over a 200-year period.
Some of the mounds are 3 m (10 ft) tall and 10 m (33 ft) wide, and they are spaced about 20 m (66 ft) apart. Underneath the mounds are networks of tunnels that required the excavation of 10 cubic kilometres (2.4 cu mi) of dirt. Scientists performed radioactive dating on 11 mounds. The youngest mound was 690 years old.
