Back to the truck location
I re-listened to the video by attorney David Schmidt and re-read the written report. Schmidt specifically said the truck was south of Harper Flat. There is also video of someone on a dirtbike driving Fish Creek Wash and asking a passing Jeep if they had seen an abandoned blue pickup truck, a blue Toyota. The response is muffled and not clear and the dirtbike rider does not further clarify the issue other than to repeat that LE said it would have to be helicoptered out.
So no new information from CBS 8, and we are all waiting for the LE report.
That's excellent information and there are posts on the Anza-Borrego Wonders FB page with similar info.
Using the basic Park road map (see below), it seems to me that if the truck is SOUTH of Harper Flat, the only way to get there is by Pinyon Canyon road which then turns into Hapahapa Flat Road and then into Fish Creek Road. The sign may just say Pinyon Canyon Road because that's apparently popular.
To get to Pinyon Canyon, one an take the red and yellow highway which is the Historic Corridor and recommended for first time visitors to the park OR the Plum Canyon turnoff (which may be actually signed as Pinyon Canyon). ANYWAY, they would have been pretty close to Julian (for the ping) if they did it either way.
So, they go up south of Harper Flat (and I see that there's a drop off point for hikers to hike across Harper Flat/into Pinyon Wash. At one point, that road becomes a one way road - so you either have to stop at the Drop Off point and turn around - or continue onward over many small roads to one of two main routes back to a "main road." I figure it's one way because it's too narrow to have two-way. I don't know where this alleged fence is.
I can think of some "issues" that drivers would face up there. If continuing on to the section that's one way going east and if deciding that was a mistake, what does one do? Make an illegal turn and try to go back, hoping there's no oncoming traffic? Back up the road as far as possible (which is likely legal, although dangerous) and find a vantage point to observe when to put one's truck back in the two-way section?
It's odd but the only other case of this type that I've read about (newish truck badly damaged by fall off the road) involved an attempt to back up, wherein the driver miscalculated where his rear tires were and both went off the road - whole truck ended up in a heap far below. Since we know they needed a copter to take JRF's truck out, I can easily imagine such a fall. But then what?
They'd be near Harper Flat and if they had this park map, they might try to cross it and walk out via Pinyon Wash. Pinyon Wash would be slightly more visited than most of the rest of that area, so a good choice. They could also have just walked back along the road and tried to flag someone for help, as well. That one hairpin turn looks like a doozy. If that's where the crash occurred, then the two passengers (possibly injured?) were very close to Harper Flat and to Pinyon Wash.
This is the standard map given out by the park to visitors, AFAIK. As the crow flies I figure it's about 6 miles, across Harper Flat, down Pinyon Wash, to Highway 78. Looks like they made it as far as Pinyon Wash to me, given what we know. It's looking to me like poor judgment in roads chosen, being on a narrow mountain road, and crash the truck to the point where it was inoperable. While the crashed truck is only noted after the Hurricane, IIRC, this theory has it that the pair lost use of it on July 24 or thereabouts and tried to walk out. Whether it was move by water, later, will help the Coroner figure out some theories. I'm guessing no cell service until they get near the bottom of Pinyon Wash.
There are a bunch of youtubes about "Pinyon Mountain Trail" (and some of those feature offroading in Pinyon Wash). But here's one that is of Pinyon Mountain Road (the first little bit is further up the road, but it shows how a regular dirt road becomes...well, I've linked it below the map.
