We'll visit Pacifico Mountain from Mill Creek Summit using a combination of the PCT and fire roads. This area was burned in the Station Fire (2009). The summit area is a pleasant campsite; the twin highpoints are challenging granite boulders. 12 miles, 2200' gain.
It's a fairly long drive from the Sport Chalet to Mill Creek Summit, about 45 minutes, so carpooling will be prudent.
Rain/snow cancels. I'll give a weather update later in the week.
