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.

本数据集伴随了Dethier与Lazarus（2006年）对约940平方公里科罗拉多州（美国）前山脉地区风化层分析的研究。数据源自1872年存档于科罗拉多州水资源部门（丹佛办公室）的钻井日志记录。本研究涵盖了Allens Park、Eldorado Springs、Gold Hill、Nederland、Tungsten和Ward等地区所有可解读的记录。我们记录了覆盖层、冲积层和高度风化的风化层厚度，以及总风化厚度、新鲜基岩深度、总钻井深度以及钻井员的备注。随后，我们利用ESRI ArcMap在地形图上对钻井位置及其相关数据进行数字化处理。数据集中任意钻井的最大可能位置误差约为1/16部分的面积（大约0.16平方公里）。详见Dethier与Lazarus（2016年）对方法的详细描述。
