We will get an early start out of town Saturday morning to beat the heat.  Game plan is to meet at the Phelps Creek TH around 8:30 for the approach via the Carne High Route.  We'll try to tag two peaks on our way to our camp at Leroy Basin (thinking Chilly and Ice Box, both top 200'ers).  Sunday morning we'll get rolling early to tag Fernow and hopefully start the hike out before it is too hot out there.

It is going to be real hot this weekend - forecast says 107 in Leavy at the moment - so we are going to get early starts to avoid the worst of it and stay up high during the day on Saturday.  This will fundamentally be a scrambling trip with just a touch of steep snow in the Gloomy Glacier basin on our way over to Fernow.  Mainly we will just be doing a lot of hiking with full packs in the heat.

So this trip will demand excellent fitness.  If you are interested in it, please detail your climbs this season or other into on your fitness practice so that climb leader knows you are ready for what this itinerary will require.
