This is absolutely not true in low humidity areas. I live in Northern California and hike all summer in 95+ temperatures. Be smart in choosing your hikes and carry plenty of water and you'll be fine.

People die every month in 'low humidity areas' while hiking in 90F - 100F weather. A woman hiking with an experienced date just died in Phoenix, Arizona.

I'm in the heatstroke camp, but I don't think this is a good comparison. The woman who died in AZ had just flown in from Boston, which can lead to dehydration. Neither she or her date brought water with them and he abandoned her partway through the short hike.

Agree. I would not be surprised if alcohol wasn’t also a factor.

I’m a big hiker and I don’t know any serious hikers that drink before or during a hike. Maybe afterwards to celebrate a strenuous hike, but not during.

Same. I also don’t drink the night before a strenuous hike. I was referring to the woman in Arizona who died hiking after a flight from Boston.

Okay you cannot call yourself an experience hiker and not bring water with you on a hike in Arizona. Also abandoning your partner is a big no no

I think PPs meant that they don’t drink alcohol before or during a hike (in response to the other PP who speculated that alcohol was a factor in this situation).

I watched it. It wasn’t clear if he meant the water in their bottles or water in the river. It sounded like the latter. He goes from the poisonous algae blooms to the test results.

I think he’s talking about anatoxin in the River because he says he reported it to the water boards and warns the public about the presence of algae blooms.

I know it's totally off topic, but they were hiking on a date and he just left her halfway through? So weird.

How far was the river from the trailhead? They probably hiked down there and rested and cooled off in the water. The anatoxin sickened them.

Websleauths poster:

"Mariposa County has a history of illegal marijuana grows. The illegal growers are known to use toxic and often deadly chemicals to ward off animals, and perhaps people? I do wonder if this family stumbled upon a grow and deadly pesticides. Word now of an 'unknown hazard' off the trail where they were found has me really focused on this. I'm still of the mindset that this was poisoning, intentional or not.

'Unknown hazards' found on Sierra National Forest trail near where Calif. family was found dead

“Some of the pesticide is so concentrated animals die in a matter of minutes, if not seconds,” said Forest Service researcher Craig Thompson."

Wow, this is from Wikipedia:

Despite the relatively low frequency of anatoxin-a relative to other cyanotoxins, its high toxicity (the lethal dose is not known for humans, but is estimated to be less than 5 mg for an adult male[30]) means that it is still considered a serious threat to terrestrial and aquatic organisms, most significantly to livestock and to humans. Anatoxin-a is suspected to have been involved in the death of at least one person.[15] The threat posed by anatoxin-a and other cyanotoxins is increasing as both fertilizer runoff, leading to eutrophication in lakes and rivers, and higher global temperatures contribute to a greater frequency and prevalence of cyanobacterial blooms.[20]

Maybe fertilizer runoff from the marijuana growers and the heat caused super high levels of toxic algae bloom. Can be ingested orally, by inhalation, or skin.

The sheriff I think was saying there’s that toxic algae in the river. He also said they’re still pursuing all avenues and the FBI is helping them a lot. If it was a slam dunk case of toxic algae bloom, he would have said it.

Wow so it WAS THE ALGAE BLOOM. Holy crap.

The toxin, called anatoxin-a (ATX) or Very Fast Death Factor (no, we're not kidding), does what it says on the tin - kills things fast. If you are unfortunate enough to be exposed it can cause a loss of coordination, paralysis, or death in humans and other animals.

"ATX is one of the more dangerous cyanotoxins produced by harmful algal blooms, which are becoming more predominant in lakes and ponds worldwide due to global warming and climate change," explains first author James Sutherland from the Nantucket Land Council.

Oski was an older dog so I doubt he took off so far in the heat that his owners would have to chase him down.

8 isn't that old. And if he saw a critter he may have chased...
