Summary
This section of the data release includes drillhole information in the format of a comma-separated value (CSV) file (2018LakePowellCoring_DrillholeInfo.csv). It is Part 1 (of four) in this data release and represents the broadest hierarchical information on the dataset including the drillhole name, location, water depth, sediments top and bottom, drillhole depth, and recovery for each coring location. Each drillhole comprises multiple cores which are outlined in “Part 2 – Core and core section information from the 2018 coring project in Lake Powell, Utah” (2018LakePowellCoring_CoreSectionInfo.csv) of this data release. Core logs and spectrophotometry data are available in “Part 3 – Multi-Sensor Core Logger and spectrophotometry logs [...]

Purpose
Cores were collected to characterize the sediment that has deposited in Lake Powell and determine the presence, if measurable, of metals associated with the 2015 Gold King Mine release in the San Juan River delta. Data further provides empirical evidence for volumetric studies in sedimentation and storage capacity.
