Muir Snowfield Update 9/4

As we transition into September, the Muir Snowfield is becoming more of an "Icefield" than a snowfield.  The majority of the hike beyond Pebble Creek has exposed glacial ice with a number of open crevasses above 8500'.  Where there is snow, the surface conditions are quite sun cupped and capped with a fine layer of rock and dust.

The crevasses that are present on the upper portion of the snowfield are easy to spot and navigate around, but caution should still be taken as the surface condition adjacent to these features are firm and icy.  Take caution while descending from Camp Muir, as a couple of these cracks can be difficult to spot from above.


While navigating the Muir Snowfield, we recommend bringing sturdy footwear that are capable of accepting micro-spikes or crampons which will greatly aid in security.  Trekking poles are also very useful!


Water is present around the lower rock outcroppings as well as on the top of Moon Rocks.  Beware though, as the Muir Snowfield sees a large amount of traffic and filtering the run-off is highly recommended.

Safe Climbing!
