On a 4 mile, 2000+ ft ascent.
Still low in elevation with the still green Aspens.

My pack was a low 22.75 pounds of weight.
Just two nights of food, 2 liters of water.
Exchanged my 1.5 pound fleece jacket for a lighter down jacket.
and saved 3-5 pounds by leaving any big camera behind for the small phone for picture taking.
