 This is a conditioning hike so participants should be in good condition to hike on a fairly steep grade at a steady moderate pace (1.5 mph up, 2-2.5 mph down) with few rest stops.  Please do not sign up for this hike if you haven't hiked at this pace on a strenuous route comfortably in the recent past.

Follow the weather forecast at   It looks like we will have snow showers mixed with rain showers, so good raingear, non-cotton layers, warm hat and gloves, and sturdy waterproof footwear with thick grippy soles are a must.  This trail can be icy and slippery at the top so microspikes are required.  Trekking poles are a very good idea as some parts can be slippery.  We may have to turn around if conditions get too treacherous toward the top.
