Summary
This section of the data release includes core images in the format of photos (JPG) that have been compressed into a zipped file (2018LakePowellCoring_CorePhotos.zip). It is Part 4 (of four) in this data release and contains images of the cleaned archival half from split cores as they appeared immediately after splitting (late March and early April 2019). Each photo includes a ruler (in centimeters) and X-Rite ColorChecker Classic color correction card that may be used for corrections. Drillhole information, such as location and total recovery, are outlined in “Part 1 – Drillhole information from the 2018 coring project in Lake Powell, Utah” (2018LakePowellCoring_DrillholeInfo.csv) of this data release. Each drillhole comprises multiple [...]

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.
