This dataset contains the results of 13 individual (U-Th)/He analyses using zircons extracted from bedrock samples collected from medium-high grade metamorphic rocks along the Simikot transect in western Nepal. Bedrock samples were collected for thermochronologic cooling ages to better constrain the exhumation history of the western Nepal Himalaya. Analytical methods followed the general procedures outlined in Reiners (2005, doi:10.2138/rmg.2005.58.6) and Reiners et al. (2004, doi:10.1016/j.gca.2003.10.021). The data table contains results for each zircon grain measurement (three per sample) and includes the mean age for each sample, calculated from three zircon grains, and an error that spans the range in measured ages and includes a 2σ analytical error.
