FRESNO, Calif. — Last month two men and their teenage sons tackled one of the world’s most unforgiving summertime hikes: the Grand Canyon’s parched and searing Royal Arch Loop. Along with bedrolls and freeze-dried food, the inexperienced backpackers carried a personal locator beacon — just in case.

In the span of three days, the group pushed the panic button three times, mobilizing helicopters for dangerous, lifesaving rescues inside the steep canyon walls.

What was that emergency? The water they had found to quench their thirst “tasted salty.”

If they had not been toting the device that works like Onstar for hikers, “we would have never attempted this hike,” one of them said after the third rescue crew forced them to board their chopper. It’s a growing problem facing the men and women who risk their lives when they believe others are in danger of losing theirs.

Technology has made calling for help instantaneous even in the most remote places. Because would-be adventurers can send GPS coordinates to rescuers with the touch of a button, some are exploring terrain they do not have the experience, knowledge or endurance to tackle.

Rescue officials are deciding whether to start keeping statistics on the problem, but the incidents have become so frequent that the head of California’s Search and Rescue operation has a name for the devices: Yuppie 911.

“Now you can go into the back country and take a risk you might not normally have taken,” says Matt Scharper, who coordinates a rescue every day in a state with wilderness so rugged even crashed planes can take decades to find.

Hikers are arming themselves with increasingly affordable technology intended to get them out of life-threatening situations.

While daring rescues are one result, very often the beacons go off unintentionally when the button is pushed in someone’s backpack, or they are activated unnecessarily.

“There’s controversy over these devices in the first place because it removes the self sufficiency that’s required in the back country,” Scharper says.

The sheriff’s office in San Bernardino County, the largest in the nation and home to part of the unforgiving Death Valley, hopes to reduce false alarms. So it is studying under what circumstances hikers activate the devices.

“In the past, people who got in trouble self-rescued; they got on their hands and knees and crawled out,” says John Amrhein, the county’s emergency coordinator. “We saw the increase in non-emergencies with cell phones: people called saying ‘I’m cold and damp. Come get me out.’ These take it to another level.”

Personal locator beacons, which send distress signals to government satellites, became available in the early 1980s, but at a price exceeding $1,200. They have been legal for the public to use since 2003, and in the last year the price has fallen to less than $100 for devices that send alerts to a company, which then calls local law enforcement.

When rescue beacons tempt inexperienced hikers to attempt trails beyond their abilities, that can translate into unnecessary expense and a risk of lives.

When eight climbers ran into trouble last winter during a summit attempt of Mt. Hood in Oregon, they called for help after becoming stranded on a glacier in a snowstorm.

“The question is, would they have decided to go on the trip knowing the weather was going bad if they had not been able to take the beacons,” asks Rocky Henderson of Portland Mountain Rescue. “We are now entering the Twilight Zone of someone else’s intentions.”
