From: A 2,000-year reconstruction of the rain-fed maize agricultural niche in the US Southwest
These maps show the proportion of years (AD 1–2000) each location is in the rain-fed maize agricultural niche. More shaded areas are in the niche more often. In the VEPIIN study area (a), the Mesa Verde cuesta (lower-right quadrant) is in the niche more than 90% of the years in the last two millennia. In the VEPIIS area (b), portions of the Pajarito Plateau (lower-left quadrant) are also in the niche more than 90% of the years. Scale bar, 10 km.
