Brief report:
An excellent autumn day in the San Francisco Peaks range: sunny, clear & crisp, no wind, yellow and fiery orange aspen leaves. Downside was dozens and dozens of tourists. Drove out of Phoenix at 7:00am. Arrived at the Humphrey's Peak trailhead at 9:20am. Started the hike at 9:32am, summited at 12:12pm. Spend 35 minutes at the summit....had excellent views all-around (e.g. Grand Canyon to the north). Left summit at 12:47pm, back at my car at 2:15pm (about 4hrs 45 min roundtrip). Drove through Sedona on my way south to Phoenix. Great day to be out.
