Hello.
My family and I actually live about 60 miles due west of this area, so we are locals paying attention to this case.
My spouse and I used to live in Yosemite Valley as we worked there, we also used to drive that highway daily to and from work after we moved out of the Valley and into Mariposa town.
We know quite a bit the terrain very very well, we had worked as part of a labor crew rebuilding campgrounds along the Merced River downstream.

We are not liking the suspicion of "Toxic Algae Bloom" very much. Having lived in and around the area for many years, and now living in area with local ponds and two lakes, Algae Bloom happens all the time. It takes really high amounts of it to kill humans, and although "Toxic Algae Bloom" can be inhaled, again, it would take incredibly high concentrations of it to kill rapidly all at once.
We camped one weekend many years ago at a campground right next to the lake at Salton Sea, spent all night breathing that air, woke up to hundreds of dead fish along the lake shore (now THAT was a terrible smell) BUT we did NOT die from those fumes, even at such high levels.

If we go back to the carbon monoxide theory from the air from the mines — there is an odd, overlooked possibility. So, where we live in the foothills, we have roads going uphill and down and around the bends. We can drive along the top ridge of the hill and fry in 110 degrees F, go down the hill and through a narrow section between hills and drive through an air pocket of cooler air - air cooled being in the shade on the north side of the hill all day. That cool air does not move very fast or at all when the winds do not blow. So an air pocket could have formed in the apex of the "V" section of the trail where the family was found. That "V" section - those parts are known to have water draining between the sections of hillside meeting together, it could have an opening to an underground spring. If the air does not move very fast from lack of winds moving air pockets around, underground gases could have collected and formed an air pocket there, which they all could have breathed. If the winds blew overnight and dispersed the gases, no trace of the gases would be found present.

There is one more thing that is often very much overlooked and that is there is a possibility of an underground volcano fissure along that area. The name "Devil's Gulch", "Devil's Peak", and further south east — "Devil's Postpile", an area of basalt columns formed by volcanic activity right next to June Mountain and Mammoth Mountain, known dormant volcanos — right on the other side of Yosemite NP.
So, following that angle from "Devil's Gulch" along to where the South Fork of the Merced River meets the main river channel — if you keep going straight NNW along hwy 49 to where Hwy 49 meets highway 108, actually where highway 108 meets highway 120 west of Jamestown, there is an area called "Red Hills Recreational Management Area" — that section is actually the visible rim of a blown volcano. And it blew fairly recently in the last 1000 years as down the road from our house there is a rock from that volcano sitting in a field and minding its own.
But South of the area of "Devil's Gulch" along the area known as "Bootjack" (Where the heck is "Bootjack"?) there is a residential area of Mariposa County formed by Midpines, Triangle Road, Tiptop Road, Darrah Road, etc. And, my spouse, while growing up, lived in many different houses and rentals as his family moved around a lot for cheaper rents. There are houses where, on one section of the mountain, the well water contains high amounts of iron in the water and there are some sections where the water contains high amounts of sulphur - and sulphur in the underground water is a high indication of a volcano fissure.
It is highly likely that after several of the fires, the earth movement of that huge rockslide at Highway 140 back in 2006, a lack of trees or shrubs to stabilize the soil on the hillside, a fissure opened up and released some toxic gases. It need be no larger than a 1-foot-wide x 1-foot-long crack to release gases from an underground fissure. It can go undetected for years as this hiking trail is not heavily traveled, or if winds are blowing and constantly dispersing gases.
But, we locals, are thinking that, with all the family and the dog dead at once - they would have had to have been exposed and died very quickly. And, just because there are few mines in the area does not mean there are no other underground fissures or channels present.

And that’s what we have so far, until further investigation is revealed.

I believe poisonous gases (“chemicals”) are one of the few things that have been ruled out, which would include CO (technically a chemical compound) and sulfur. CO, at least, would show up as carboxyhemoglobin. They were also found 3 miles away from the nearest mine:

“Since the discovery, authorities have struggled to explain the cause of the tragedy. But on Thursday, the sheriff's office officially ruled out two causes: exposure to chemicals along the trail the family were on, and use of a gun or another deadly weapon.” 2 Causes of Death Ruled Out as Investigation into Calif. Family's Mysterious Deaths Continues

From the SF Chronicle: “Investigators said Thursday they have ruled out exposure to chemicals from a mine along the trail and use of a gun or other weapon in the mysterious case of a former San Francisco family who died along with their dog on a remote Mariposa County hiking route.” Investigators have ruled out 2 causes of death in case of Mariposa family, but still have no answers

@FlowergirlinWard1 did mention that "if the air does not move very fast from lack of winds moving air pockets around, underground gases could have collected and formed an air pocket there, which they all could have breathed. If the winds blew overnight and dispersed the gases, no trace of the gases would be found present."

So this could be the case if they couldn't find traces or exposure to gases if it has been blown away if it had been a one-off odd occurrence.

I think that one of the reasons that poisonous gases may have been ruled out is the belief that they would have found dead animals in the vicinity, if there had been some sort of deadly outgassing.

CO would show up on autopsy even if there was no trace of it left in the air (carboxyhemoglobin). I’m not sure about other gases, but I’m taking LE “at their word” and trusting that they did their due diligence before dismissing chemical exposure as a COD. Volcanic gases (H2S) smell like rotten eggs so the family definitely would’ve noticed it; it’s not an “invisible” threat.

I really want to hear about outgoing calls/texts or voice recordings. I have to assume that they didn't all expire at exactly the same time, because, if they did, that would be one point in favor of the alien/supernatural/Stranger Things theories. So, at some point, one of them should have realized the potential risk of death. Unless of course, the lack of effort to reach out could be explained by the confusion caused by the heat. But, even that wouldn't occur at the same rate in both adults, right? I just feel like one of them would/should have realized their lives were in serious risk in enough time to try to reach somebody or at least leave a clue/send a message. If that didn't happen, whatever killed them was fast and happened at the same rate in both adults. I am having trouble accepting that.

I would be shocked if there were no attempts to call for help, because (as you said), there should have been at least a few minutes where one adult realized that the other was declining. Anecdotes of heat exhaustion progressing into heatstroke don’t describe it as a sudden blackout where you’re rendered suddenly incapable; you feel hot, thirsty, need to sit down, and then it progresses into heatstroke where confusion sets in (and you may not even be thirsty anymore).

It’s not uncommon for heat to affect hiking partners differently; I read a case recently where someone’s partner collapsed on a trail, they called for help, but their partner died before help arrived. The caller was OK, physically speaking. I would be surprised if a 30 year-old yoga practitioner had the same heatstroke risk as a 45 year old.

Being new to these threads, I took a lot of the numbers about temperature and where they would be on the trail that were mentioned in various places at face value. I just assumed they were accurate.

But since I have absolutely no life, I found time to run through all that data. And if they did a straight hike as many believe, I don’t see how any of them would have encountered temperatures over 100 degrees on that trail, let alone 106 or 109.

To judge times on the trail, I used the standard Naismith’s Rule for hikers, hill walkers, etc., which is 1hr for every 3mi, plus an additional hour for every 2000ft of climb.

The route from the trailhead on Hite Cove Road begins at 3900ft elevation and drops down to the river at Nutmeg Gulch (1800ft) covering 2.5 miles. (Source: https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5344035.pdf )

The level route on South Fork Trail from Nutmeg Gulch along the river to the base of Savage-Lundy Trail is 3.1 miles. (Source: Hiking on the Savage Lundy Trail | Sierra News Online )

The hike from the signpost on the South Fork trail up Savage-Lundy Trail is 3.0 miles and an ascent of approx. 2100ft. (Source: https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5344038.pdf )

The relevant temperatures on 8/15/21 at the Jerseydale weather station (elev. 3900ft) were:
8am: 82F
9am: 84F
10am: 89F
11am: 91F
Noon: 94F
1pm: 95F
Source - Jerseydale California

The relevant temperatures that day at the El Portal weather station (elev. 2050ft) were:

8am: 85F
9am: 92F
10am: 99F
11am: 103F
Noon: 107F
Source - El Portal California

They’re seen approaching the trailhead at 7:45 that morning. If they start the hike at 8am, it would be 82F where they are at the top. They would be down at Nutmeg Gulch on the river by 8:50am before the temperature got to be 92F. Then they would cover the level 3.1 mile trail along the river in an hour. But I’ll be conservative and add in 10 minutes for water breaks and maybe a diaper change.

So by 10am, and they would conservatively be at the base of Savage-Lundy Trail, ready to head up back to the truck. The temperature would be 99F.

Up to that point, they have only hiked for 2 hours, with breaks, on downhill or level terrain. The temperature over that time has spanned from 82F to 99F. And they’ve had immediate access to the river if anyone wanted to quickly dunk in or wet their clothes.

So far, that’s a mild to moderate hike on a hot California day with a cool river nearby.

According to Naismith’s Rule, it should take them 2 hours to hike up the 3 miles of switchbacks (3 miles plus 2000ft ascent). But it’s hot and sunny, so I’ll be extra conservative again and tack on an extra hour just for very frequent stops to rest and hydrate and snack. That is a generous 3 hours to hike 3 miles.

They would be halfway up, at elevation 2900, at 11:30am. The temperature at the top of the trail (3900ft) would be 92-93F at 11:30. The temperature at the bottom where the started the climb would be 105F at 11:30. The temperature in the middle would again be around 99F. And that’s presuming a very leisurely stroll of 1 hour of hiking intermixed with an additional 30 minutes of nothing but stopping, resting and hydrating along the switchbacks.

The last 1.5 miles would take another conservative 1.5 hours with stopping and hydrating along the way, arriving at the top by 1pm.

The temperature at the top at 1pm was only 95F. So during the last 1.5 miles of hiking to the very top, they would have been experiencing cooling temperatures as they went.

What am I missing? How did we all think they would have been on the trail down below during the times it was over 100F?

MOO

As people said earlier on this thread, a phone might be disabled by the type of heat they would have been experiencing. So, setting aside the issue of no reception, they might have seen a dead phone when they tried to text out?

Definitely MOO, and subject to correction by people who know more about phones.

I would be surprised if a 30 year-old yoga practitioner had the same heatstroke risk as a 45 year old.
There are a number cases of hikers in their 30s dying from heat stroke:

29 year old Carrie Romero became disoriented around 2:30 p.m. on Wednesday. Search crews arrived quickly, but Romero was pronounced dead around 3 p.m. after being found about half-mile from the trailhead.

Pinal County officials said the death is heat-related. Romero had been hiking for more than 3 hours and appeared to have ample water.
Several hikers die on Arizona trails; officials urge caution

32 year old hiker dies from suspected heat stroke in Utah's Zion National Park after complaining of heat exhaustion at the end of a strenuous 9 mile canyon trail in 95 degree heat.

When Park Medics & EMTs dispatched to Wolfe’s location, they found him unresponsive, and administered CPR to no avail for about an hour, officials said.

Hey guys!

My husband of all people brought this case to my attention so I haven't yet read the whole thread. I'm about to go read starting at post 1 but just a quick question if y'all don't mind indulging me... do we know if LE has inspected the home? Also, could this be a murder suicide using some offbeat chemical? It's okay to throw some tomatoes at me but not too hard (or rotten) please. :eek:

Certainly there is an explanation that just hasn't yet been found but in the meantime it's quite the mystery. I look forward to seeing all your theories! Off to read now...

To be clear, I’m not saying that 30 year olds can’t die from heatstroke - they certainly can - just that I don’t think the risk to a 30 year old fitness devotee would be the same as the risk to a 45 year old. My point was that, if the risk is not exactly equivalent, there should be a window of time where one adult is aware of the other adult declining and is prompted to call 911. I find it unlikely that heatstroke would have incapacitated both of them at the same time.
 
  • #815
Seeing these images I would say that it is extremely improbable that they drank from this brew. Perhaps the dog, but not the humans, esp. the baby.

But would the whole river look like that?
 
  • #816
When there are too many variety of reasons to have caused their death, that's most unlikely the answer to the real cause.

Because I have a far simpler and reasonable scenario than all the theories many are putting out here.

Acute oxygen deprivation - they hiked through an high altitude gulch region where oxygen is severely lacking and atmosphere pressure is high causing them to fight for life.

I don't know if anyone has mentioned this theory yet but not sure it'd show up in their autopsies.

It’s not like it’s the Himalayas. There’s no reduced oxygen there.

Agree. And sort of my point. Thanks.

A lot has been surmised from JG's AllTrails history. Although he and EC were said to hike regularly, only a couple of JG's hikes were recorded at AllTrails after May. As a software engineer, you might think he would still be tracking these hikes somewhere. I found some accounts at Strava and MapMyFitness that looked like theirs but they were either set to private or had no activities logged there. Those apps aren't real popular with most hikers anyway. Is it possible their hikes were being logged somewhere else?

Supposedly JG researched Hites Cove on an app the day before. It is marked "completed" in his AllTrails but it is unclear when that refers to. Are there other apps he might have used for research? It's also possible they hiked but didn't log many of their recent hikes anywhere, just to disconnect a bit from the world.

What I'm trying to understand is if they were acclimatized and familiar with hiking in that area in very hot conditions. And had they gone on recent hikes together with the baby and dog?

Apart from that, the most recent AllTrails hikes for JG looked to be of shorter distances, less than 5 miles generally. There were roughly equal numbers of loops and "out and back" hikes. So there was no real indication of what was suggested earlier, a compulsion by some hikers push on to complete loops.

Family friend said "they hike on weekends"
Entire family reported missing, later found dead in Mariposa County

I'm also wondering if there was analyzable data from their truck. It might indicate when they actually arrived and started their hike if nothing else.

Said to drive a 2020(?) Ford Raptor. Maybe it was equipped with GPS/wifi hotspot?

One recent one was a 13 miles hike.

I hike 3 -4 times per week, usually 1.5 to 2.5 hours. Bigger hikes are 4-5 hours.

I don’t log anything.

Do we know the altitude of the place where they died?

Do we know the altitude of the place where their car was parked?

Do we know the altitude of their home? That would provide, I would think, a baseline for their acclimatization.

If we know these, I think we can either consider this theory, or totally dismiss it.

The Mayo Clinic, as I interpret this link, seems to take 8000 feet as more or less the starting point for altitude sickness risks. I’m sure people, with their variability, can get sick at lower elevations, but I wouldn’t think that young and healthy, (assuming that they were healthy,) people would be at much risk.


All this my opinion only.

Elevation there is under 2000 ft.

Didn’t LE say toxicology might be back as early as today? I guess not yet because I can’t find any updates.
