Written Report:
We toured in to the Hayden Glacier, and ended up skiing off the small promontory between Middle and North Sister (I've heard this called Prouty Pinnacle or Point before). We saw no signs of current instabilities with the exception of some smaller roller balls on the South face of North Sister emanating from exposed boulders and cliffs. There was an older D1 Wind Slab crown high on the East Face of Middle Sister that was likely from late Sunday or Monday.

Similar to Aaron's experience at Ball Butte on Monday, most of the snow we skied above treeline was wind effected from transport down glacier. That being said it was still soft enough for pleasant skiing. The one exception to the soft wind packed snow was the steeper East-South-East face of "Prouty Pinnacle" which had a melt freeze crust due to its more southern exposure and steepness.

Throughout our tour the sky was completely clear. Winds were mostly calm or light on the glacier with some lightly blowing snow. However, it was easy to see that on the peaks, ridgetops and even "Prouty Pinnacle" the wind was strong from the South-East with plumes of snow extending into the air from each summit (Moderate to Intense blowing snow).
At 2:15 pm on the Hayden Glacier at 8710 ft. the temperature was -2 C
The surface snow was comprised of 1mm wind battered grains. Boot Penetration was 20 cm.
