Abstract

Eight trips were made to Snoqualmie Pass, 63 miles east of Seattle, between Dec. 27 and April 4, 1940. Profile cuts were made in the snow, temperatures were taken at various depths, and dye solutions were poured over the snow to test permeability. Snow fall was normal during the 1939-40 winter. Two cold spells occurred and these produced impervious crusts. No important crusts developed after January. A graph of the various crust layers and their movement during the winter and melt season is shown and described in the text.
