Size ~2 slide with long runout on the backside of the West Lion yesterday, likely due to the collapse of a cornice from the summit. Heard a loud boom on the hike around 12:30. Photos at 3:30pm.

Great conditions on the Spearhead today. Travel was fast and ski quality was generally good! Soft up high but nice melt-freeze crust around treeline. A few noticeable pockets of wind-slab but we didn't see any activity. Curtain Glacier on MacBeth skied very nicely. Banana Chute on Fissile was firm. A bit colder than we expected and pretty windy at times but nice to see the sun!
