“…A proglacial lake (0.08 km 2 ) near the glacier terminus formed prior to 1981 and with further glacier retreat another lake (0.04 km 2 ) formed around 2005. Peyto Glacier had an area of 13.98 km 2 in 1948 (Mlynowski and Menounos, 2012). By 2006, Peyto Glacier disintegrated into two separate glaciers that cover an area of 11.16 km 2 (Fig.…”

Reliable, long-term records of glacier mass change are invaluable to the glaciological and climate-change communities and used to assess the importance of glacier wastage on streamflow. Here we evaluate the in-situ observations of glacier mass change for Place (1982–2020) and Peyto glaciers (1983–2020) in western Canada. We use geodetic mass balance to calibrate a physically-based mass-balance model coupled with an ice dynamics routine. We find large discrepancies between the glaciological and geodetic records for the periods 1987–1993 (Place) and 2001–2006 (Peyto). Over the period of observations, the exclusion of ice dynamics in the model increased simulated cumulative mass change by ~10.6 (24%) and 7.1 (21%) m w.e. for Place and Peyto glacier, respectively. Cumulative mass loss using geodetic, modelled and glaciological approaches are respectively − 30.5 ± 4.5, − 32.0 ± 3.6, − 29.7 ± 3.6 m w.e. for Peyto Glacier (1982–2017) and − 45.9 ± 5.2, − 43.1 ± 3.1, − 38.4 ± 5.1 m w.e. for Place Glacier (1981–2019). Based on discrepancies noted in the mass-balance records for certain decades (e.g. 1990s), we caution the community if these data are to be used for hydrological model development.

“…Sediment outputs are then Figure 3.3: Sum of observed sediment yield from the lake and delta. Lake yield is an average of interpolations from sediment cores by two different methods (Thiessen poly gons and splining) and smoothed using locally weighted regression [Mlynowski, 2013]. Ice extent is measured from air photos over the past 60 years and a 1917 map of the area.…”
