We put a large group of 16 climbers up on the glacier Tuesday. There was a storm blowing in so we were not able to land them on the snow at the 6000′ elevation as they had hoped. We generally use wheel skis to access the glaciers during the summer months, as long as optimum conditions prevail. Optimum conditions mean winds less than 20 knots and enough sun light shining on the snow to create shadows. The storms at altitude are usually more severe with winds well in excess of 50 knots. The non-de script landscape of snow covered glacier makes it nearly impossible to deal with marginal weather because all visual reference is lost in the flat light of white on white. we opted for 35″ bushwheels, rather than wheel skis, because of the stormy outlook, and landed on the exposed ice of the lower glacier. The wind was still blowing 30 knots but the air was still very smooth as long as you stayed away from the mechanical turbulence associated with close proximity to terrain. It took us most of the afternoon to move everybody in, but when we flew away at the end of the day they were well situated for the weather and cooking dinner in 30 knot winds.
