Hassan Basagic, a glacier researcher at Portland State University, has been making a series of comparative photos showing glacial changes in the Cascades. He came across the Loomis-Baker comparison photos taken by E.D. Welsh (1912) and John Scurlock (2012) and posted on this website a couple of months ago. Hassan sent the photo below, showing the Boulder Glacier (left side) and Park Glacier (on the right) from 4640′ on Boulder Ridge, which extends eastward from Mount Baker between Boulder and Park Creeks. The upper photo was taken by J.E. Booen (also spelled ‘Boen’ in some documents) during the first ascent of the Boulder Glacier route by the ‘LaConnor Expedition’. Hassan’s documentation says the photo was taken in 1892, but according to John Miles’s account of this ascent in Koma Kulshan (a history of human involvement with Mount Baker), this ascent was made in 1891. Hassan’s photo was taken this past fall (2012). The retreat of the Boulder Glacier is remarkable. It is not possible to measure the length of recession, but the decrease in ice thickness is clearly many tens of meters.
