Emmons-Winthrop Route

This route is still straightforward despite the late start to the climbing season. However, the weather has been fluctuating drastically, rapidly changing the snow conditions, covering crevasses one day and starting to melt them out the next. It apparently doesn’t matter that the summer solstice has already passed, avalanches have still been occurring on the upper mountain.

Things were looking a bit thin on the upper mountain back in April, when we had unusual high temps and dry weather. However, climbers and skiers will be psyched to know that the May and June-uary storms have really helped refill the upper mountain this last month. The Emmons-Winthrop saw it’s first ascents of the season last week and it is as good as it gets for late-June. There have even been a couple of ascents and descents of the Winthrop shoulder, though the cracks opening up down low warn that it wont last long if the high temperatures remain.

As seen in the photo, the route goes straight up the Corridor which has only a few cracks opening up right now. It then traverses right, across a thick "fin" which feels solid in the morning when it is frozen, but maybe makes one pause and contemplate a possible quick belay on the way down when conditions soften. After the fin you traverse over to the Alpine Meadows and head almost straight up to the summit, crossing several long troughs in the snow that hint at the large crevasses that will open as the weather gets hotter and drier. Look carefully for the safest crossing, especially on the way down, for it looks as though a couple of boots have already broke through sagging bridges to the crevasse below. As of now the route goes around left over the large bergschrund seen near the top of the route from camp.

It is important to note too that June still has some storms left before we hopefully hit the high pressure that marks true summer in Washington. With these unusually cold storms there were a number of avalanches that occurred during and even a couple of days after despite the intense solar radiation. Whumphing has been heard around the Cowlitz and Camp Muir long after we would usually suspect storm or wind slabs lasting this time of year. A climber triggered a significant avalanche on the Turtle Snowfield Monday, two days after the last storm. Several wet slab crowns (one that occurred 24 hours after a storm) can be seen on the Winthrop Glacier at approximately 10,000’. They occurred on a ~40 degree southeast facing slope. As the weather continues to fluctuate, stay tuned to what is happening on the upper mountain the days before your climb and don’t let go of those avalanche assessment skills even though summer is officially here.

As for the approach to Camp Schurman, it is easy walking all the way to Glacier Basin with just a few patches of snow to cross; tennis shoes or light hikers are recommended. Switch to skis or mountain boots and continue up the basin (watch out for creek holes) and up the Inter Glacier. The Inter is still relatively smooth for this time of year, though it has not been freezing completely overnight, and there are a couple of crevasses starting to open.

Plan and prepare for your trip so that you can have an awesome climb - read the terms of the permit carefully, check the various weather resources to get an idea of the conditions you'll encounter, and revisit the blog here for any updates.  We look forward to seeing you on the mountain!
