Desert Dan,
We have certainly trod some of the same trails over time. I remember you posting on here a few years ago about Baja travel. I have in a briefcase marked Baja, every one of the ACSC brochures and maps you show, except one. I have not opened it for 30 years...but it's still there and has made several moves. I do have the 18"x48" Baja map by McMahon's cartographer carefully folded up in the briefcase. We made a lot of trips to Baja and pretty much covered the northern 3/4's of the area. The most remote place I have ever been in my lifetime was a 1974 trip to Malarimo on the west coast, on the obvious hook on maps. First you had to get to Guerro Negro and stock up on provisions (mostly beer and gas). After passing the Tropic of Cancer(?) at El Arco you head west on the loneliest 150 miles of dirt track, driving over dunes and on tracks of Pemex trucks (oil exploration from the 1950's) across the Vizciano Desert (the driest desert i have ever been in and I lived in the desert for some years) down endless rocky arroyos to Rancho San Jose del Castro. This was about the half way point. There was one old pickup parked there and a herd of burros and some horses for local travel. Saddles were lined up on wooden racks. A ranch hand tried to sell me some gas but we had 80 gallons on board. I asked to at least see the gas and it was in a 55 gallon drum mixed with dirt, water, rust, and goat droppings so I declined. We finally got to Malarimo (loosely translated: bad to get to) as it is the flotsam and jetsam capital of the world. Shipwrecks, dead marine animals including whale skeletons littered the endless beach. Scammon's Lagoon is more to the east and is the crib/spawning ground for the California grey whale, AK to Baja migration.
Below is 4WD #3 that took 5 men on that trip:
1970 Toyota Land Cruiser, FJ-55, Chevy 307 c.i. V-8, 3 on the floor, Hone overdrive, 4.11's, 53 gallon replacement gas tank, 2, 5 gallon racks on tailgate, power steering and brakes, Air conditioning, 11x15 Armstrong True Trac tires, Power Lok L.S., Warn 8K winch on tomba burro. ConFer Toyota jeep trailer with locking lids and 4 gas can holders, so 83 gallon capacity.

In the middle of the Vizciano, a trailer main spring snapped so we ditched the trailer in the desert to be picked up somehow on the return. When you lose the main spring the axle wants to locate against the fender and stop rolling. We removed the entire axle from the trailer, removed all contents and put it up on the tomb burro with tongue on the roof and repacked the trailer including the axle (which Ralph Sauer is dead lifting like a weightlifter). The only woe was seeing where you were going. Both front seat occupants traveled with the doors wide open and leaning out to see around the trailer body 100 miles back to Guerro Negro. We did look a sight slowly moving into to town, hanging out the doors trying not to run over any ninos. A local mechanico found some old chevy pickup springs that he crafted, blacksmith style into the mix. He worked all day and wanted $7 whole dollars, US, for his time. Yes, he got a lot more than that. While we were waiting there was a Rodeo with lots of caballeros strutting their stuff, Mexican style, so we took in the festivities. What a culture warp to be a part of that scene.

The rest of the trip included Bahia de Los Angeles and Bahia Gonzaga on the east side. Water temp on that side in September was 88 degrees, F.
