Thanks for posting those links. Reading about wet bulb temperatures and our bodies helps me understand heat stress better. Wikipedia has useful information too. Beyond about 95 degrees wet bulb, our bodies are not capable of cooling down even naked in the shade with a fan! Instead we heat up even more and die.

This also explains why San Diego often feels hotter than other places in SoCal even though the dry bulb temperature is much lower.

This also helps to understand why warming of just a few degrees can make parts of the world uninhabitable.

It’s too hot today. I am in LA.

At very high humidity and heat, only wearing an ice vest or drinking ice water works.

Interesting that heat is the big killer. Not what you would expect from national news coverage.

The science behind that is as interesting as it is accurate. Kind of an unfortunate name...

If you recall the Beijing Olympics, I remember at the time being concerned that the conditions were potentially dangerous. Looks like they were at the very threshold of what even a skinny marathon runner can withstand. I'm glad they all survived. Go back and look at the stats at the time and at the graphs on the links Perry posted - they were running at maximum effort in the red to black level for several hours. Could have turned out very badly.

There's a mounting consensus that the marathon should be run during the winter Olympics to enhance the chance for a world record. How about they make the change simply to avoid fatalities? Just sayin'

I'm late to this post, just had a chance to read Perry's posting of the wet-bulb guide--what an eye-opener. Of course I knew humidity had a negative effect, but I had not known how even just a little increase of humidity can push you into the life-threatening black zone when temperatures are very high, as they are here. That graph was 'chilling'.

btw Zip, I know you wanted me to message you re picking up that book--and thank you!--but I can't seem to leave a PM for you. :(

On average RMRU has about 50 missions a year. This year has been quite busy as we just had our 50th mission. Another successful rescue of three hikers near the top of San Jacinto Mountain.

Rescue No. 1

Three years ago a guy started hiking in July at 10AM [As per P.E], the tram was closed due to maintenance and repairs. He tried to return the same way, and got off trail. He must have run low on water and lit a signal fire to attract attention in Palm Springs to his plight. He started a forest fire and was rescued by helicopter.

Other challenging and worthwhile hikes are the Vivian Creek trail up to Mt. San Gorgonio from Forest Falls – 16 miles round trip with 5300 ft of elevation gain. The Bear Creek Trail from Baldy Village to Baldy [Mt San Antonio] – 16 miles round trip with 5700 ft of elevation gain. Less strenuous hikes can be found in the Indian Canyons in Palm Springs and Mt Baldy from the Falls Road at Manker Flats. Ice House Canyon below the Ski Lift Rd. is also well worth the trip.

Rescue No. 2

Mountain rescuer Rick Maschek of Hesperia packs up his gear after the Riverside Mountain Rescue Unit rescued lost hikers from the mountainous area of the Aerial Tramway in Palm Springs. The hikers were reported missing on Monday evening and were found Tuesday morning.

What you should take on a hike depends on the weather conditions and the expected length of your hike, but the American Red Cross recommends that every backpack contain:
A Cell Phone
A Compass
Extra Socks
First Aid Kit
Extra Food
Rain Gear
A Flashlight

Six hikers were rescued Tuesday morning from Mount San Jacinto in Palm Springs after they were overcome by icy conditions on the Skyline Trail, which runs from the Palm Springs Desert Museum to the top of the mountain.

No one was seriously injured, although one woman suffered a sprained ankle and one man tripped on the ice and cut his forehead.

"They thought they were prepared, but they weren’t prepared," said Terry Greenstein, vice president of the Riverside Mountain Rescue Unit, which was called in Monday evening to rescue the hikers. "I think they expected snow, but they didn’t expect ice."

Greenstein said the hikers did not have the proper equipment to traverse the icy trail, but when they realized that, it was too late: The hikers couldn’t get off the mountain without help.

The volunteer rescue unit was called into action about 7 p.m. Monday when three hikers, using a cell phone, called for help on the Skyline Trail. A short time later, a second group of three hikers on the same trail called for help as well.

"They’re lucky they were on the same trail," Greenstein said.

If not for that, the rescue unit would have had to divide its resources to find the two groups of hikers. As it was, the unit was able to coordinate the two rescue efforts.

The first group, described by rescuers as two men and one woman from San Diego in their late 30s or early 40s, was found at about 7,800 feet. Rescuers simply rode the Palm Springs Aerial Tramway to the top of the mountain, hiked down to them and then led them out of harm’s way on foot around 1 a.m. Tuesday.

The second group was more difficult to find. Dana Potts, a member of the rescue team, said rescuers couldn’t locate the other group in the dark. The rescuers hunkered down for the night while the three hikers made a fire to stay warm.

After dawn, the rescue unit called in a helicopter to locate the hikers and rescuers. The hikers were airlifted out after 8 a.m., the last of the rescuers after 10 a.m.

Rescuers said the second group was found at about 7,400 feet and was composed of two men and a woman in their late 20s, all of whom are stationed at Camp Pendleton.

"They were all triathletes," Potts said.

Said Greenstein: "I think both groups were very happy. The second group was more embarrassed."

Rescuers said to avoid situations like this, hikers need to be prepared for all kinds of weather conditions. The hikers had hiking boots with only four spikes on them. The rescuers had to use boots with 10 or 12 spikes in Tuesday’s conditions.

"When you’re dealing with winter weather hiking" Greenstein said, "the conditions can change in 10 minutes.

"They weren’t prepared for the conditions."

A friend of mine named Ellen Coleman, was rescued by helicopter eight days ago from the top of Mt San Jacinto after breaking a leg on an icy patch and then crawling for three miles on hands and knees in a raging blizzard up to the shelter on top of the peak. She spent two freezing nights there before search and rescue found her.
