Abstract
During the summer months of July and August 1989, approximately 23 years after a photogrammetric survey on August 22, 1966, Peyto Glacier was re-surveyed using terrestrial geodetic surveying techniques. The volumetric and morphologic change of Peyto Glacier, Alberta from 1966 to 1989 is estimated through a combined application of digital cartometry, digital geodetic survey and Triangulated Irregular Network (TIN) digital terrain modelling and analysis. Changes in glacial volume, areal extent, terminus position, percentage basin glaciation, slope, and aspect for the 23 year interval are shown. The volumetric change of Peyto Glacier is estimated to be -154.6 10\6\rm m3 and compares favourably with the figure of -155.3 10\6\rm m3 obtained through a directly measured accumulation/ablation stake network. The surface area of Peyto Glacier 1989 is estimated at 12.04 km2, a loss of 1.07 km2 from the 1966 surface area of 13.11 km2. The terminus of Peyto Glacier has retreated 592 m. Amaximum of 86 m vertical loss was measured in the ablation zone.
