The data presented here were produced to study glacial and glacio-fluvial catchment erosion using 'tracer thermochronology' where detrital downstream samples can be used to infer the source elevation sectors of sediments when integrated with known surface bedrock ages from the catchment. For the first time, our study used the zircon (U-Th)/He (ZHe) method as tracer thermochronometer. The samples come from the Leones Valley at the northeastern flank of the Northern Patagonian Icefield, Chile (46.7° S) This data set comprises ZHe analytical results from (i) six detrital samples of different depositional age and grain size (622 single-grain analyses in total), and (ii) two previously analyzed (Andrić-Tomašević et al., 2021) bedrock samples (22 single-grain analyses in total), as well as grain size measurements and lithology identification of two of the detrital samples (two pebble samples with 262 and 211 pebbles, respectively). Data are provided in 10 tab-delimited text files. The full description of the data and methods is provided in the data description file.
