We left Tucson around 9 am, and arrived at the Desert Diamond Casino/store in Why, AZ on AZ-86 just East of AZ-85 around 11.30 am. It was almost lunch time so we decided to eat there. There were a few table outside that were poorly shaded but it was OK in December. In summer, it would not be a great place to picnic unless the sun is behind the building. After lunch we drove to the starting point and planned on using the route provided by Matthias S. Thanks to Matthias for uploading a route. We ended up taking another route but we used the same starting point.

We noticed a gate that was a few hundred feet from our parking area, further up the road. We did not see a 'no trespassing' sign and we even saw a place where it was possible to step through the fence next to the gate. It appeared to be private property, but nobody was there at this time. We saw some nice organ pipe cactus on the property and also along the hike. We found a rusted old car near the side of the road and stopped to get photos. We walked by an old house and got a better look at the summit and the best way to get there.

We looked up and saw a small saddle so we decided to walk there. There wasn't much brush the the incline was not steep. After reaching the saddle, we could see the summit better and there were a few ways to get there. We could either stay on the same ridgeline or drop down and pick up another ridgeline heading in the direction of the summit. But, we felt it was probably more direct to stay on our current ridgeline to get up to the main ridgeline. When we got to the main ridgeline it got quite rocky but we were able to follow it upwards. There was one section up ahead that we could not clearly see. It turned out to be fine. Nothing over class 2.

After 1.1 miles, we unexpectedly ran into a good trail! This was a pleasant surprise! A few minutes later we ran into another hiker coming down. She was from Washington state and in the Ajo area visiting a friend and hiking. We traded a few stories and talked for about an hour! After that we continued on the well-maintained trail and that took us all the way to the summit. At the summit, we found a registry with about 20 pages of entries going back about 11 years. We signed the registry, had a snack and decided that we would take the trail all the way down on the way down.

From the summit, we could see most of the town of Ajo, the mine, and the mine tailings. Looking Northwest we could see Childs mountain which had an antenna tower on top. This is another 1K prominence peak that I would like to hike someday.

We didn't know exactly where the trailhead was or if there even was one. But, the trail going down was very well-maintained. Near the bottom, we saw some building and we could not tell if those buildings were commercial or residential. There were some branches but we decided to stay on the main branch of the trail. The main branch of the trail led us into private property, but we were not aware that it was private property until we saw a 'no trespassing' sign on the North end of the property. There didn't seem to be anyone there.

It would have been better to take one of the right branches of the trail on the way going down. I traced what I believe was a better route and plotted it on my GPS track. See 'alternate starting point' on route. It would be possible to park here and start from this point. Then, you would have a really nice trail that would take you all the way to the top.

Route notes:
1. Rectangular boxes are private property
2. Southwest of the 'alternate starting point', the topo map shows a 4x4 road. This road appeared to be blocked.
3. There are multiple track segments. Why can't they be shown in different colors?

This was actually two different hikes, both of which were to summits near the town of Ajo:
1) Childs Mountain: elevation of 2,880 feet and prominence of 1,240 feet
2) Peak 2976: elevation of 2,976 feet(duh!) and prominence of 1,116 feet

Childs Mountain
(7.8 miles with an AEG of 1,268 feet)
This hike was a road walk. I drove in on Childs Mountain Road for about 3.25 miles off of Highway 85 on a very well graded unpaved road. I parked at a locked gate that had a sign saying that vehicular access was prohibited but that pedestrians and bicyclists were OK.

After walking on the gravel road for almost 2 miles I came to the boundary for the Cabeza Prieta National Wildlife Refuge. Childs Mountain is in the refuge, and a Barry Goldwater range access permit is needed to go there. I had a permit and had checked in online to the Cabeza Prieta NWR so I was good to go. The road became paved once entering the Cabeza Prieta NWR. The road led all the way to the summit, which is easy to spot since there is a large radome on top that is visible for miles around. The radome was built back when the Ajo Air Force Station (AFS) was established during the cold war days. The highpoint is just outside the west side of a chain link fence that surrounds the radome.

I checked out the views and took a break before heading back.

Peak 2976
(3.0 miles with an AEG of 1,309 feet)
Peak 2976 is in the Little Ajo Mountains, and it is a mile or so west of the town of Ajo. I had no beta and no GPS tracks for this hike, so I wasn't sure if it would go or not.

The peak and my route are on BLM land, although there was a small parcel of private propery west of my route that I made sure to circumvent. I had used route cloud to identify and ridgelet and a ridgeline to take, but I wasn't real sure how to get there and what I might encounter once I did get there. It actually worked out as good or better than what I was hoping for.

I parked along FR8112G, about 200 feet before getting to a locked gate that is on private property. I am usually apprehensive about driving on a forest road with 4 numbers and a letter appended to the numbers, but this one was a good road. I don't think that I would drive a sedan on it, but it is suitable for about any crossover SUV when dry.

From my parking spot I went south on an old roadbed which morphed into a use trail. Before going into a wash, I made a right turn and made a short climb to a saddle. From there I went over to a second saddle, losing and regaining a bit of elevation in the process. From the second saddle I could see the ridgeline that I wanted, and the ridgelet that would get me up to the ridgeline. It was a steep, but fairly short, climb to the ridgeline. There were some rocks and boulders to deal with, but nothing more than class 2.

Once on the ridgeline, I was about 1/2 mile from the summit. I went southeast on the for 1/4 mile, and then the ridgeline curved south for the last 1/4 mile. There was some fun rock scrambling for the first 1/4 mile. Sometimes I was on the ridgeline, and at other times I was either on the left or right side of the ridgeline, often going back and forth. There were a few sketchy places, but they were easy to get around and I did not do anything worse than class 2. Once I started going south in the last 1/4 miles, I was on a good use trail that went to the summit.

There was a summit register log at the summit, and most of the entries were from local people, so this hike seems to be popular with Ajo residents. I enjoyed the nice, expansive views at the summit and went back the way that I came. On the way back I could see that the use trail went off to the east; if you could figure out how to access the use trail that might be the best way to do this hike.

Synopsis
There were nice expansive on Childs Mountain and along the way up and down the mountain; however, it is still a road walk which wasn't all that exciting.

I really enjoyed the hike up to Peak 2976. There is some route-finding involved which kept things interesting, and the scramble along the ridgeline was fun. Nice views at the top didn't hurt either!
