Checked out the glide avalanche on the West face of Pyramid that released sometime before 10:30 am. We had brief window of visibility and took a quick road observation lap before touring up the standard Tincan up-track to 2100′. The rain line was 1750′. We saw some small avalanche activity off of CFR ridge and some active wind loading. No major avalanche activity observed on the non-motorized side. Seattle Ridge is littered with debris piles. Some appear more recent and many are from the weekend. There was a new wet slab on Seattle Ridge south of Bertha Creek campground. There was roller balls on easterly aspects getting affected by the sun. Cornices are large.
