Glacier Benito is a temperate outlet glacier on the west side of the North Patagonian Icefield. Rates of thinning and ablation were obtained using data collected in 1972/73 and subsequent data collected in 2007 and 2011. Ice-front recession rates
increasing between 2007 and 2011. Increases in ice movement and ablation were negligible. Ice front recession along the glacier's centre line from 1886 to 2002 was approximately 1860 m. Thereafter glacier asymmetry makes measurement along the glacier centre
line unrepresentative of areal change until 1998 when symmetry was restored. From 1998 to 2002 the rate increased dramatically. Recession from the southern end of Benito's terminal moraine in the 1850s supports an early date for initial retreat
