Mt. Fitzherbert

Recent observations: Scientists from the Cascades Volcano Observatory made observations July 8, 2008 of Crater Glacier including the co-joined west and east arms of Crater Glacier north of the 1980s dome. They mapped along the northernmost part of the west arm that has advanced about 20 m since May 30, 2008. The advancing glacier ice has moved a bit into the gullies that have been carved by erosion into the Pumice Plain. Calculations from digital elevation data suggests that about 10-11% of the volume of Crater Glacier has been removed over the course of the eruption. Despite incommodious environs at times durning the eruption, Crater Glacier persists, now flanking the 1980s dome on the west, east and north.
