This dataset comprises three tables containing infrared stimulated luminescence (IRSL) ages and related data from samples collected at seven terrace sites along the Totatlanika River in central Alaska in 2020 and 2021. The IRSL ages and data were generated from the samples at the Utah State University Luminescence Lab. The ages were determined to enable computation of rates of bedrock incision along the Totatlanika River. The file "geology_BurialDating_IRSLSiteData_Totatlanika_bender_2022.csv" contains site locations in the NAD83 reference frame, and incision rates computed from listed field-measured terrace heights and IRSL depositional ages of terrace sand. The IRSL age data, in turn, are stored in the file "geology_BurialDating_IRSLAgeData_Totatlanika_bender_2022.csv" and are computed in part from raw data contained in the file "geology_BurialDating_IRSLDoseRate_Totatlanika_bender_2022.csv". Data in all files are linked by the "Sample" field.
