We've been watching this glide crack open slowly over the last week of warm weather. It finally released sometime last night. Below is a progression over the last three days of the crack opening, getting bigger and finally avalanching.
The first two were taken Thursday afternoon 4/10. You can see the crack opening in the middle left of the first photo.
On Friday we saw the warmest temps so far this season and also 3 days in a row of superficial or no refreeze overnight. This was taken at 4pm Friday 4/11 and you can see that the crack has nearly doubled in size in 24hrs.
These last photos were taken Saturday 4/12 at 07:00. The avalanche likely happened sometime between 4pm and 6:30am. Glide sure is an interesting beast.
