In 1967, the city changed its government to elect four of the seven city council members from single-member districts or wards, rather than at-large. This enabled a broader representation of voters. As with many major urban areas, the city core began losing population to the suburbs in the 1960s (the peak population of 208,982

216-555: A trading post called the Cantine was established next to the mound (by then known as the Great Nobb). It lasted only until 1784. In the early 19th century, the land was claimed by people of French descent, and Nicholas Jarrot had a deed for most of it. He donated some to a small group of French Trappist monks, who settled on one of the smaller mounds from 1809. They took advantage of the big mound's terraces to grow produce, which

288-516: A 5-foot-thick (1.5 m) coal bed. By 1876, this mine employed 150 men and shipped 20 carloads of coal per day. By 1885, numerous mine shafts were within the city limits, and mining began to spread into the surrounding countryside. By 1893, 23 mines were in the region. By 1908, Des Moines' coal resources were largely exhausted. In 1912, Des Moines still had eight locals of the United Mine Workers union, representing 1,410 miners. This

576-441: A series of anti-slip "steps" across the exposed face before the original earth (minus the imported repair material) was replaced at its original level. To avoid introducing water deep into the mound's interior, the work was carried out in high summer, and as quickly as possible.

Ramey, who bought the site in 1864, began an era of more responsible ownership, and encouraged archaeological investigation. Many artifacts were found at or near the surface. Ramey had a tunnel made nearly 30 m (98 ft) into the north face of the mound, but it revealed nothing of historic interest. By this time, people were beginning to consider

1440-424: The 1980s and 1990s were only partly successful. In 2004-5 more serious slumping episodes occurred. These demonstrated that adding new earth to repair the major slump on the east side had been a mistake. Experts decided to take a new approach. In 2007, backhoes were used to dig out the entire mass of earth from this slump and another at the northwest corner, to a level beyond the internal slippage zone. Engineers created

Botanical remains from Monks Mound suggest it was built much more quickly than previously thought, perhaps on the order of several consecutive decades, providing an alternative view of its construction history. Deep excavations in 2007 confirmed findings from earlier test borings, that several types of earth and clay from different sources had been used successively. Study of various sites suggests that

3096-518: The mound more within its context. A survey made for local dentist Dr. John R. Patrick in the 1880s marked the beginning of modern understanding of the Cahokia site as a whole, and its relationship to other sites in the area. Many archaeological investigations of the mound have taken place since then. One of the biggest began in the 1960s, when Nelson Reed, a local businessman and historian of native cultures, obtained permission to conduct excavations. He

3168-482: The mound's summit, which was the evidence by which they could place and evaluate artifacts and construction. Reed's backhoe excavations revealed other significant features, such as a hole, which seemed to have been the socket for a post about three feet (one metre) in diameter.

3384-426: The problem. In 1984-5 there were several slumps, and the state government brought in surplus soil to make repairs to the major scar on the eastern side. A decade later, there was further slumping on the western side, so irregular that repair was impractical. Drains were installed to reduce the effects of heavy rain. It was during this process that workers discovered a mass of stone deep within the mound. The repairs of

Unlike Egyptian pyramids which were built of stone, the platform mound was constructed almost entirely of layers of basket-transported soil and clay. Because of this construction and its flattened top, over

3744-469: The site. The most recent section of the mound, added some time before 1200 CE, is the lower terrace at the south end, which was added after the northern end had reached its full height. It may partly have been intended to help minimize the slumping which by then was already under way. Today, the western half of the summit plateau is significantly lower than the eastern; this is the result of massive slumping, beginning about 1200 CE. This also caused

3816-473: The stability of the mound was improved by the incorporation of bulwarks, some made of clay, others of sods from the Mississippi flood-plain, which permitted steeper slopes than the use of earth alone. The structure rises in four terraces to a height of 100 feet (30 m) with a rectangular base covering nearly 15 acres (6.1 ha) and containing 22 million cubic feet of adobe, carried basket by basket to

The illegal whiskey trade, combined with the destruction of traditional lifeways, led to severe problems for their society. One newspaper reported: "It is a fact that the location of Fort Des Moines among the Sac and Fox Indians (under its present commander) for the last two years, had corrupted them more and lowered them deeper in

3960-536: The time the original urban society collapsed, the great mound became overgrown with trees, the roots of which helped stabilize its steep slopes. In the 20th century, researchers removed the trees in the course of work at the mound and park preparation. Reduction of groundwater levels in the Mississippi floodplain during the 1950s caused the mound to dry out, damaging the clay layers within. When heavy rainfall occurred, it caused new slumping, starting about 1956. The increasingly violent weather of recent decades has exacerbated

This quickly revealed various features, including what appeared to be the outline of the temple. Further backhoe work in 1971 confirmed the shape of the presumed temple at over 30 m (98 ft) long, the largest building found at Cahokia. This technique was opposed by professional archaeologists because it destroyed several hundred years of stratification over most of

It may have led to the abandonment of the mound's high status, following which various wooden buildings were erected on the south terrace, and garbage was dumped at the foot of the mound. By about 1300, the urban society at Cahokia Mounds was in serious decline. When the eastern side of the mound started to suffer serious slumping, it was not repaired. There

Its designed dimensions would have been significantly smaller than its present extent, but recent excavations have revealed that slumping was a problem even while the mound was being made. Construction of Monks Mound by
