apatite from granite samples out of the little cottonwood stock of north-central utah range in age from about 7 ma at 1500 m elevation to about 11 ma at 3500 m elevation and give an uplift rate of 0.68 mm yr** $minus$ **1 during this time period. zircons from some of the same samples range in age from about 9 ma at 1500 m elevation to 20 ma at 3500 m, and probably represent an uplifted partial annealing zone. the uplift is associated with movement along the wasatch fault which borders the stock on its western margin. the calculated uplift rates from the apatite ages in this study agree well with rates found by other workers along the central segments of the wasatch fault using a variety of methods.
