Sears Point
We wanted to get an early start on the Sears petroglyph site, so Carrizo Overlook was an easy choice. The ground flowers were everywhere, so we enjoyed them while having coffee, before getting back on highway 8 towards Yuma.
The traffic wasn't bad on the 80 miles to Yuma. After a fuel stop, we took about half an hour to get to the turnoff for Spot Road. Our plan was to go about 5 miles in and find some decent place to camp, just before the washboarded road runs into the sand washes that were once the Gila River. We had e-bikes with 2.3 inch tires to do the remaining 2 or 3 miles to the Sears Petroglyph site. We camped on a solid desert pavement flat spot, across from some off road types with a generator and toys. Plenty of room for everyone and they were friendly. It was a little windy, but not to the point of blowing sand yet. We unloaded the bikes and got going.

The views were expansive and the horizon seemed endless. Once we got to the sandy sections, Kathy's and my riding styles became somewhat different. Her philosophy was to go to level 5 (the max) pedal assist and go fast enough to stay on top of the sand as long as no mistakes or whims of fate took her by surprise. My approach was to use level 3 and struggle a bit more with the front end taking off this was or the other. She had a big smile whenever I would catch up.

We got to a few muddy parts and had some question about our intended goal, but made it to the signed site without too much trouble. Locked the bikes together behind some trees and proceeded to the info boards. We had seen no one to this point, and everything was open dirt except for some marginal fences to keep OHV out.

Painted Rock and Three Rivers Petroglyph Sites
Three Rivers New Mexico and Painted Rock in Arizona
We actually drove the 5 hours from SD to Painted Rock first, but thought I'd better lead with my best picture. This beautiful lady looks back at you from 600 years ago at the Three Rivers Petroglyph site in New Mexico. There is a cool thing about basaltic rocks (from an upheaving volcano) and their life in the desert. They take on a "desert varnish" from weathering and provide a great canvas for someone with artistic talent and a stone or two. As you pick at the rock, it becomes a canvas. The Three Rivers art is realistic, in contrast to the San Francisco or La Rumorosa style. The spiritual journeys of the medicine men in Baja and San Diego were carried out in remote, dark, lonely spots best frequented by snakes and other vermin. The sites I am about to describe are a more social and less introspective variety. Painted Rock in particular is "more Facebook" as my better half noted.
We get to the Painted Rock turnoff by exiting Highway 8 on a road by the same name. We are a little road dazed, but manage to fill out the BLM fee envelope and get spot close to the rock mound that is the centerpiece to the the campground. We are happy to be somewhere and start unpacking the bikes and other gear we will be using. We have 10 days, so no big rush. It is a typical BLM campground with vault toilets, big trash cans and paths around the central pile of rocks with more petroglyphs (scratch the desert pavement not paint) than I have ever seen anywhere.
I am pretty stoked about the Gila River thing. It was the way the early pioneers went westward without dying in larger numbers. The Gila was the basis for the Great Southern Route to the resort city of San Diego. It had shade, potable water, and animals to sacrifice for the good of westward expansion. The next day we took off on our Rad City e-bikes to explore the Gila River and pioneer history. Unfortunately, the road to the Gila River Dam terminates about 300 yards from the earthen dam. Darn, Homeland Security wins again over any attempt to see water in the Gila River. No Trespassing! We go back toward the campground and go west by the corporate alfalfa fields, waving at the operators of $100 K tractors. At the end of the fields on the south side there are 6 javelina (Pecarry) taking it to the man by eating the highly green alfalfa a la carte. They jump around at our excitement and seem more like teddy bears than aggressive wild boar.

So, I didn't get any pictures of the peccary. I only had an iPhone, not my weapon of choice, the Panasonic sx60 with a bigger telephoto lens. Three subsequent trips to the same field yielded zip on the same subject.
So, let's talk a bit on the pictographs at Painted Rock. They date from 7,000 BC and contain the archaic style (mostly geometric patterns) to the Gila Style with human forms and anthropomorphic images with other parts added. Don Lipponi, who wrote "La Rumorosa Rock Art Along the Border" recommended an iPhone app "iDstretch", which helps to bring out faint pictograph or pictoglyph images. For me, it is kind of a poor man's Photoshop ($6).
This is a mix of the archaic and Gila styles
The thing about the Painted Rock site is that it has art from the earliest markings (7000 BC) and those that are in the Hohokam occupation from 50 BC on. The first artists were desert survivors who gathered plants and had occasional meat. At about 9000 BC, the large animals such as elephants, bison, horses etc. died out from climate change not caused by petrol dependency. Anything that looks vaguely like a human is not the archaic period, think ladders and geometric designs.
The e-bikes gave us a break from the tourists going around the big rock pile that is Painted Rock. We kept trying to catch the pesky pecarrys, but to no avail. The major volcanic mountain toward the west is Oatman Peak. We braved the washboard and uncertainty for ten miles or so out into the volcanic desert pavement and traded power levels for the lead in this endeavor. It was a pounding ride without rear suspension, but you use what you have.

Beauty in the Lava
We spent 4 days at Painted Rock to a mostly deserted BLM campground. Though we were there in early December, it was the warmest part of the trip with big starry skies. The next stop was a short hop to Lordsburg, New Mexico for a shower and Subway. Got to Three Rivers Petroglyph site in late afternoon the next day and scored a BLM with electricity to run our little 1500 watt space heater. Life is good.

Archaic Period Pit House
As you can see the pit house style of home ownership is pretty basic. You put some twigs, mud over the top and have a small hole in the middle to let the smoke escape. The Mogollon culture in the early period were hunter gatherers who moved through the southwest as opportunity presented itself. The village site is to the east of the hills that contain the petroglyphs. They were originally a mountain people, tough and resourceful. Their art style is often quite realistic, as can be seen from the lead photograph. As farming became another source of food, the hunting and gathering still made them more independent than other groups that relied on river flooding exclusively. After crossing about 10 signed rivers with no water running (unless you count the New River, which is really disgusting), I think our infatuation with dams has reached a logical conclusion.
Many of the petroglyph have patterns within the main figure.
The mountain sheep were a prey that was highly prized.
There are over 20,000 petroglyphs at the Three Rivers site. I chose it from a book titled "Rock Art Along the Way" by Janet Farnsworth. She gives a thumbnail descriptions of sites you can visit in the southwestern states. A more formal description of current knowledge and best guesses of the experts is "The Archaeology of Ancient Arizona" by Reid and Whittlesey.

4 Nights and 5 Days over Cottonwood Pass with my brother Marty
I hadn't been backpacking since going with my brother a few years ago, so was happy to join him in another Sierra adventure a few weeks ago. Our trip started at Cottonwood Pass and the last night I took this picture of my tent at 11,000 foot elevation as the moon was setting.

We had originally planned to exit at Kearsarge Pass, but changed our itinerary when the Onion Valley hiker parking lot was more crowded than either of us had ever seen. We decided to learn more about this area that is a little south of Whitney. I have identified each camp we made while doing the Cottonwood to New Army Pass loop on the map below.
The last camp is south of the marked location, near Long Lake
We left the truck at 4 pm and got over Cottonwood Pass just before dark. A helo had been circling around the pass for about 20 minute and was at Chicken Spring Lake at dark when we arrived there. It was a very tight takeoff, with bright lights flashing and very noisy. A young woman had altitude sickness or a diabetic episode and her father called in the rescue. It was probably very expensive but a good decision.
Helo takeoff
When Marty did the PCT in 1979, the route from Kennedy Meadows followed the flat contour of many giant meadows that led to Siberian Pass and then joined the current PCT route. We did a day hike from our second camp below Major General Mountain to the Siberian Pass for old times sake. It is not used any more to preserve the fragile meadows. Marty did a 17 day long slog without reprovision in snowy weather and deep snow, exiting at Kearsarge Pass. I remembered that a with a friend we had attempted delivering the resupply with some search and rescue assistance. We didn't make it over Kearsarge Pass in avalanching conditions, but that's another story.

The meadow in front of our camp below Major General Mountain was pristine and very wet. There were many marmots and no other campsites could be seen. We stayed at a large, flat camp with great views and easy water access.
We got an early start on New Army Pass to avoid the heat and accomplish the 2000 foot elevation gain with the rising sun. We had the pass to ourselves until almost at the top.

Great view of the south side of New Army Pass
The New Army Pass is quite a perch. It's south aspect is nearly vertical and is a tribute to the trail builders non existent fear of heights. The second lake in the chain was the site of our last camp. It was a perfect night for gazing at the stars and reflecting our good luck to live in such a beautiful world. God bless whoever saved this wilderness for the future.
Backstory:
The last time I had backpacked was about two years ago. Kathy, Marty and I did about 70 miles on the John Muir Trail. By the end of the backpack, I was peeing blood and my fingers had started cramping up from all the stuffing, putting the tent up and down, and getting in and out of the bear canister. The way my fingers would freeze up in odd positions was quite comical, but kind of a show stopper. Kathy started doing a lot of the work to help me out, so I knew that a few senior adaptive techniques were in order to make me more self sufficient.
First, rather than use the small bags and cramming the sleeping bag or tent into them, I used some winter stuff bags that have straps that use buckles to cinch down the load. Second, bought a small pair of pliers to deal with the velcro tabs in my self supporting Black Diamond Bibler tent and the straps on the stuff sacks.
Dehydration was probably the source of the pee problem on the last backpack. For some reason, I don't drink well on the move. On this trip I got the idea to wake early and drink a quart before getting out of the tent. This saved the water weight in the pack and seemed to work much better at keeping me hydrated.
A person younger than 76 probably wouldn't have any trouble using a quarter to turn the three screws in my Kevlar bear canister that make it bear proof. After this trip, I now have a small slot screwdriver in my side pocket to accomplish this frequent task easily!
