On November 16 I explored west of Marana, Arizona, and hiked and scrambled up Silver Bell Peak, the high point of the Silver Bell Mountains. Silver Bell Peak has only 4261 feet of elevation but is the 81st most prominent peak in Arizona with 1921 feet of prominence. I got good use of my Jeep on the drive in and hiked through mostly open country.
Although Silver Bell Peak is close to Tucson I was not able to find access information for it. However, I was able to map out a driving approach to the peak using topographic software and Google satellite views. I have since posted my driving directions online here. This approach route worked well for me, although the last 2.9 miles in was rocky and rutted in spots. I recommend visitors have a high-clearance 4WD vehicle with good tires.
