What reading level is The Origin of the Cahokia Mounds book?
To quickly assess the difficulty of the text, read a short excerpt:
Hereto- fore there has not been opportunity to study the structure. Six years ago the writer was permitted to collect samples of soil from Monks' mound with a two inch auger which was sunk twenty-five feet down from the top (Fig. 22). At another time he collected soils from holes made with spade and pesthole digger in the north face. These tests showed the presence of different layers and a kind of stratification just as is evident in the mounds now exca- G rated. But they were not enough to sh...ow that the layers were themselves composed of lenses nor to make the true structure evi- dent. Moorehead and Leighton point out that the builders piled up the earth several feet and then used the mound for several sea- sons. Thus vegetation had an opportunity to take root, grow and form a soil layer rich in carbon and dark. In some instances the layer is an inch, in others many inches thick. In Asia Minor and Egypt people had a similar habit. When one house fell and was buried by its own roof or by shifting sands, another was often built on the ruins.
