Route & General Observations

Headed up the valley topping out at 2,500 feet. Some walking in boots is still mandatory down low.
While a great day out in the mountains with fresh snow, the ski quality left something to be desired. The new snow was quite heavy and moist yet still skied bottomless and had skiers hot and thirsty.
