We'll do these peaks with the aid of a car shuttle. We will visit them in the following order: Markham Peak, Mt Lowe, San Gabriel Peak (which is the highest peak in the area: 6161'), Mt Disappointment (and an optional visit to Mt Deception).
We will carpool / drive up to the end of Mt Disappointment Rd (approx 35 minutes of driving from the meeting pt); then consolidate into few vehicles to drive 2 miles to Eaton Saddle.
Optionally, some participants may elect to visit Occidental Peak: a short 2 mile, 300' gain hike.
