BCCZO -- Geology, Geomorphology -- Boulder Creek catchment and vicinity -- (2006-2006)

These data accompany the analysis of regolith weathering across ~940 km2 of the Front Range (Colorado, USA) described by Dethier & Lazarus (2006).

Collected data from 1872 paper records of well-drillers' logs held on file at the Colorado Department of Water Resources (Denver office). We used every interpretable record from the Allens Park, Eldorado Springs, Gold Hill, Nederland, Tungsten, and Ward quadrangles. We recorded the thickness of overburden, alluvium, and highly weathered regolith, along with the total weathered thickness, depth to fresh bedrock, total well depth, and any drillers’ notes. We then digitized well locations (and their associated data) on topographic quadrangles in ESRI ArcMap. The maximum probable location error for any well in the dataset is the area of a 1/16 section (approximately 0.16 km2). See Dethier & Lazarus (2016) a detailed description of the methods.
