Six people were descending Horse Tank Wash canyon: one expert, four moderately advanced, one beginner (with over 40 canyons), and one first-timer.

The last rappel of the day was a 20 ft descent off a large sandstone rock approximately 3 ft by 4 ft by 8 in thick (roughly 1,000 lbs), situated on its long edge. The webbing was brand new and inspected, with a single red sling around the rock. The rock seemed stable. Four people had rappelled on this anchor previously in the group. One person thought the anchor moved, but since it was the first time rappelling, they assumed the webbing had resituated itself. The last two decided to simul-rappel for fun.

As soon as they weighted the anchor and both people were approximately 5 feet below the sloped lip, the anchor gave out. Person A and Person B dropped approximately 15 ft to the ground below. Person A sustained a compound tibia fracture with approximately a 3-in gash, actively bleeding but not arterial. We noticed person B lay crumpled on the floor four feet away, experiencing chest and left-hand pains. Person A immediately started yelling to activate the InReach SOS due to his leg fracture. The team joined the two injured parties to assess and help with injuries.

The Garmin InReach device continuously displayed a message like “Device is damaged. Unable to send message. Contact support,” but on the main screen, it said “SOS in progress.” Because it indicated damage and an inability to send a message. We were uncertain whether it was working properly and sending the SOS signal correctly. Therefore, we decided to activate the ACR ResQLink VIEW. It clearly indicated “406 successful” and later “121.5 successful.” Although we didn’t understand the numbers, the successful marks gave us peace of mind.

Person A’s leg had splints made of branches and bandages. We transported them 30 yards down the canyon to a clearer and drier area for stabilization and SAR rescue.

There was a discussion about splitting up the group so that half could go for cell service and rescue. Person B, who owned the ACR, told the group we should stay together due to logistics. The ACR was successful, and they would come.

The group decided to stay together.

Two hours after pushing the button for the ResQLink, the first helicopter arrived, but due to high winds, it could not drop down the paramedic. The helicopter passed over three times without landing, so we decided to wait for the ground crew overnight. They were finally able to drop a paramedic at 11:30 p.m., 10.5 hours after the button activation.

Person A required rebandaging due to active bleeding and re-stabilization for long-term waiting for SAR arrival. We airlifted them out, then continued through the canyon, assisting Person B with belays, down climbs, and chest pain.

What Worked:

• The Garmin InReach eventually transmitted the name of the injured person and the nature of the injury, as well as the SOS signal (though reliability was uncertain due to error messages and phone issues).
• The ACR had two clear messages indicating success (without them, the option to split up the group for help with better signal would have been more viable, but weakening the group structure for patient well-being; the group stayed together because the ACR was trusted to get the word out).
• Notified contacts about our plans and canyon details for SAR research.
• Among the six canyoneers, one trained SAR and three had medical backgrounds, ensuring calm, organized patient care and comfort.
• Creativity, ingenuity, knowledge, and a desire to work for a good collective outcome, including knowledge of knots, moving and stacking rocks, collecting and building firewood, and keeping the patient warm.

Room for Improvement:

• Judgment error in simul-rappelling, which will never be repeated. Despite the anchor being designed to hold over a thousand pounds, it failed when the rock cleaved off the wall.
• Needed a better medical kit, specifically pressure wrapping and clotting gauze.

Thank you to all the behind-the-scenes people who made this rescue a success: friends, family, AZ DPS Air Rescue, Coconino SAR, and TRSAR. Unless you are on the receiving end, and I hope you never are, you cannot imagine the wave of elation that overcomes you when you hear those helicopter rotors in a remote canyon. When that deafening sound hovers over you, how happy you become knowing that the help you so desperately needed has finally arrived.

I have always been sincerely thankful for the friendship I have come to know and grow in this community. Despite our many differences and lifestyles, this one hobby, has become nothing short of a family.
