Tom's Thumb - McDowell Mountains

I began my hike up to Tom's Thumb at 3:47 PM. From the trailhead it took me 38 minutes to reach Vulture View Scenic Point. That was 1.2 miles. From there it was 11 minutes to Tom's Thumb Junction, and that was 49 minutes from the trailhead, and 1.6 miles from the trailhead. Then it was a 21 minute hike to Tom's Thumb. It took me 1 hour and 10 minutes to get there from the trailhead. My round-trip hike was 4.4 miles, and it took me 2 hours and 18 minutes.

Tom's Thumb is a prominent 140-foot tall Proterozoic granite monolith, formed roughly 1.4 billion years ago. Located in Scottsdale, Arizona, this quartz-monzonite intrusion stands out due to differential erosion, showcasing jagged, blocky terrain that contrasts with the smoother surrounding metamorphic rocks.
