The Stevens Pass summit is at milepost 64.5. There are four locations to be stabilized, just to the west. One is about a half mile from the summit between MP 64.1, 2/10ths of a mile to MP 63.9. The next one is a little more than half a mile further west from MP 63.2 to MP 63, at the left turn in the highway called “Big Windy”. The third location is just around that corner from MP 63 to MP 62.6, which is the first 4/10ths of a mile of the “Old Faithful” avalanche zone and the fourth is further west from MP 61.25 to MP 60.90 in the "Sandhouse" avalanche zone.
