Refined late Wisconsin chronostratigraphy of Indiana using in-situ cosmogenic radionuclides 10-Be and 26-Al. Ms thesis, Purdue University. Data comments: Sample elevations based on Google Earth. Sample thickness assumed to be 3 cm ("generally less than 4 cm thick"). Sample density assumed to be 2.65 g/cm3. Topographic shielding factors based on dip angles in Table 6-1. 10Be and 26Al concentrations calculated from isotope ratios and sample/carrier weight from Table 6-3. 10Be standard assumed to be NIST_Certified. 26Al standard assumed to be KNSTD. Sampling year assumed to be 1995. Samples Smith-Top and Smith-Bottom are separate samples from one boulder. Samples Duncan and Duncan-II are separate samples from one boulder. Samples Otterbein-Top and Otterbein-Bottom are separate samples from one boulder. Group ID based on sample location and geomorphology (13 separate groups). expage.github.io - data from expage-202306
