I took this photo of Mike shortly after he departed one of our ice strips. The transition from smooth to upheaved ice is often over a very short distance. These crevasses will never be filled with snow because they are too big of holes at too low of an elevation. In the winter the 6+ feet of snow that will fall in this area will cover the smaller cracks but leave the others exposed. Snowmachiners love to use the glaciers as a sort of highway and it is amazing to see what they have driven over the following spring as snow bridges collapse. I have seen some terrifying tracks across some awfully large gaps. I have never had a problem with snow covered crevasses and neither has Mike in his thousands upon thousands of snowy glacier landings. As I have mentioned in other posts we are usually only landing on the glaciers if the lighting is good, and part of our reasoning for that is so we can see the sags that are created as snow bridges begin to droop. If I see a dip in the Glacier you better believe I am not going to land on it.
