This 1.5 hour guided tour explores local geology and its relationship to the daily lives of the ancestral Puebloans who lived at Chimney Rock.  Rock types impact structures, pottery, tools, and soil productivity; geologic processes determine the landscape, and, at Chimney Rock, play a central role in climate.  The relationship between the pillars and the South San Juan Mountains in terms of astronomical observations will be considered.  No prior knowledge of geology is assumed.  The hike up to the Chacoan Great House may be difficult for some in terms of the steep gradient, uneven footing, and elevation.
