Time: Ceramic Period - 2,000 - 500 years ago

Sediments: About 4,400 years ago, the modern regional climate emerged, with a return of more available moisture from precipitation and surface waters, along with the modern short-grass prairie. The spring-fed stream and wet meadow marshland complex increased in size along the valley floor during the Ceramic Period, and was surrounded by grasslands. The Lubbock Lake Soil continued to develop until approximately 1000 years ago at which time it was covered by later deposits. However, not all areas were covered and the Lubbock Lake Soil continues to develop today.

Plants: Bulrushes grew along the banks of the stream. The draw was surrounded by grasslands. The presence of hardwood trees at the Landmark demonstrates the greater availability of moisture and less arid conditions than those of the Middle Archaic. However, the climate throughout this period was unstable. A basically modern climate has existed for the past 4,500 years, with minor periods of some aridity with increased temperatures and decreased moisture. A cyclical drought pattern began 2,000 years ago and continues today. As the pattern persisted, drought intervals have been more frequent and of shorter length although not of less intensity.
