Peak 4100 - Boulder Mountain Quad, AZ

The first portion of this hike is completed by following the Boulder Bob's Cabin Trail. I found it important to download and follow the GPS tracks for the Boulder Bob's Cabin Trail due to the many alternate roads one could mistakenly take and get off-track. I followed the Boulder Bob's Cabin Trail which started off as a well maintained road. However, by the time I reached the location I had decided to start my ascent, the road was nothing more than a deep washed out rut. I started the climb up 4100 at about 2.5 miles into the Boulder Bob's Cabin Trail at N33.4664 W111.44256. I bushwhacked across the terrain, crossed over the Arizona Trail and then made my way right up the side of the mountain to the south-east ridge-line. I then followed the ridge-line the rest of the way to the summit.

There are certainly some spectacular views at the top. However, the weather was not cooperating the day I chose to hike this. It started raining at the top so I didn't stay long.

For the descent I chose to follow the ridge-line the whole way down. I suggest this rout for the ascent as well. It's a little further distance but seems like it would be an easier climb. Once I reached the bottom I found the old road, or what was left of it and followed it back to the point where I pushed off for the initial ascent. It turns out that this section of the hike follows the Arizona Trail. As previously stated this portion of the trail was nothing more than a deep 4' deep rut. I would describe this portion of the trail as bushwhacking, followed by somewhat of road for while and gradually becoming better as I got closer to the trail-head.

One might consider the Arizona Trail as an alternate route to the south-east ridge line. Haven't hiked it so don't know for sure.
