This dataset contains the results of 6 fission track analyses using apatites 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. Ages were calculated using zeta 359 ± 10 (AB) for dosimeter CN-5. All ages are central ages, with the conventional method used to determine errors on sample ages.
