Lion’s Head to Platteklip: Weekend heat triggers multiple mountain rescues

1. A postcard turned pressure-cooker

Lion’s Head, Jonkershoek, Platteklip - these names usually sell calendars: ribbon waterfalls, rusty cliffs, fynbos shimmering like coloured dust.
Yet for Wilderness Search And Rescue the same three syllables now spell sprint drills, rope coils that scorch bare forearms, rotor-blades churning grit into eyes, and the soft beep of a medic’s watch while fluid seeps into a stranger’s vein.

Between one Saturday dawn and the following dusk the unpaid crew answered three full-blown mountain emergencies while the thermometer on the lower slopes kissed 38 °C and the black west-face quartzite radiated above 40 °C.
The raw numbers feel small - three events, five patients - until you zoom in: a stretcher threaded down a 60 m rock funnel, a 57-year-old woman dangling from a cable above a gorge whose only flat spot is café-table sized, two Dutch tourists so hot their words melted into gibberish.

Throw in 25 call-outs logged in December plus 13 more before January’s mid-point and the pattern is relentless: a mountain rescue every 28 hours since the holiday rush began, powered by people who clock back into office jobs at sunrise on Monday.

2. Saturday morning on Lion’s Head

• Timeline: 08:42 – 13:29*
  A 28-year-old analyst from Joburg left Tamboerskloof at dawn in slick-soled runners, reaching the first ladder just after eight.
  Powdery sand rolled like ball-bearings under her heel; she spun, her body slid, her ankle stayed.
  The crack echoed, hikers froze, a whistle chorus started the radio relay that ends at WSAR.

Eighteen minutes later a Table Mountain ranger was splinting the joint; by 09:10 a rope tech arrived soaked from sprinting uphill with 15 kg on his back.
A chopper was impossible - cable towers boxed the ledge - so the team built a twin-point anchor, shared the load, and hand-steered the stretcher down the ladder chute like a bobsleigh on rails.

She cracked a joke about “off-road Uber,” left in an ambulance at 13:29 with a pain score of six and a core temp of 37.1 °C.
Back at the parking lot the rescuers had already shed 1.8 kg of sweat.

3. Sunday furnace in Jonkershoek

• Timeline: 13:57 – 15:54*
  Jonkershoek’s shark-fin peaks funnel midday heat like a blast furnace.
  A paediatric nurse started early with 2.5 L of water, but the gorge thermometer jumped to 41 °C and shade became a moving mirage.

One slick boulder later she lay with a snapped femur, bone ends overriding, every heartbeat a hammer.
Her GP friend blew six whistle blasts a minute until rangers arrived with a vintage stretcher last used during the 2018 fires.
They rigged a vacuum mattress, started IV paracetamol and hop-scotched 400 m of car-sized boulders while a space blanket fluttered overhead like a tiny circus tent.

Air Mercy’s AS-350 slipped into a 40 m rock slot, tail rotor inches from stone, and winched her out on a 60 m line.
Forty-four minutes after the hoist started she was on an orthopaedic table; surgeons expect a full recovery within four months.

4. Platteklip’s microwave corridor

• Timeline: 16:40 – 18:18*
  Platteklip Gorge is the city’s vertical stair-master - 1.6 km, 670 m up - but after lunch the granite turns into a pizza stone.
  A Dutch couple began the climb at 14:30, each armed with 500 ml of water and a banana that looked more like a joke than nutrition.

Two hours later the woman’s core temp hit 40.2 °C, her heart racing at 148 beats, blood pressure tumbling to 88/50.
Rescuers wrapped both in evaporative blankets, poured iced water over torsos and pumped cold saline.

Carrying them down would have needed 14 bearers rotating every five minutes, so the helicopter pilot teased the skids onto a ledge two pool-tables wide while the machine remained in contact with rock to avoid rollover.
Both tourists flew out with stage-1 kidney injury; four days later they were back in the flat Netherlands, lucky to be alive.

5. The hidden casualty: volunteers

What seldom makes the headline is the heat load on the rescuers themselves.
Each volunteer humped 18 kg: harness, hardware, 30 m rope, radios, three litres of water.
Inside Gore-Tex the micro-climate soared to 45 °C; one ranger vomited from exertion, another chalked up 38.4 °C.

Post-mission weigh-ins showed an average fluid loss of 1.8 kg despite necking five litres on site.
As one veteran put it, the sole difference between patient and medic was “which side of the stretcher you woke up on.”

6. Climate, crowds and compounding risk

Cape Town’s average January maximum has crept up 1.7 °C since 1990, but the real kicker is frequency: days above 35 °C have tripled.
Add 4 % more humidity from warmer sea surfaces and the “feels-like” index now cranks past 40 °C on 18 afternoons each summer, up from six in the early ’90s.

Meanwhile Instagram tags for Lion’s Head have multiplied twelve-fold since 2014, and the cableway ferries twice the riders it once did.
End result: a mountain that is simultaneously hotter and more crowded, its rescue curve bending upward like a hockey stick.

7. New tech on the sharp end

• Phase-change vests, borrowed from F-1 pits, drop skin temperature 1.4 °C within half an hour.
• Pocket-size blast chillers flash-cool saline to 4 °C in 90 seconds, scrapping the old ice-box logistics.
• Mavic-3 drones now drop 3 kg pods of water, salt tablets and space-blankets to teams pinned down by weight limits.
• A prototype “trail threat index” crunches slope aspect, albedo and wind to spit out three-hourly heat-risk pings via WhatsApp.

8. Voices from the edge

Dr Lize-Marie van der Watt, flight medic:
“We can land a helicopter inside a gorge, but we can’t insert common sense into a human brain. Heat illness is 100 % avoidable.”

Johan Marais, rope boss:
“Quartzite polished by millions of boots owes you nothing; it will drop you faster than you can update your status.”

Nadia Abrahams, winch paramedic:
“Sixty metres of steel cable is all that sits between life and a very long fall. When I hover above that ledge I’m calculating gust margins, not likes.”

9. If you still insist on going

1. Pre-drink 500 ml the hour before you leave the car - hydrate before you dehydrate.
2. Stir a flat teaspoon of table salt into every second litre; low sodium kills as fast as heat.
3. Hit the trail at first light; if the sun can see you, you should already be heading down.
4. Download the free ResQLive app - it squirts your GPS to rescue control every 15 minutes even offline.
5. Save 021 937 0300 under “Mountain 911”; panic erases digits, seldom names.
6. Aim for straw-coloured urine; anything darker is a late red flag.
7. If you stop sweating while still moving, you are minutes from collapse - find shade, call for help, douse yourself with whatever liquid you can find.

10. The week ahead - again, and again

Forecasters warn of a lingering high-pressure ridge that will keep the Western Cape above 34 °C for the next six days, with berg-wind valleys nudging 40 °C.
WSAR has stashed extra rope kits at the lower cable station and placed a helicopter on 30-minute alert.
Models predict the heat index on north-facing rock will top 42 °C between 14:00 and 17:00 daily.

If the past is precedent, another dozen radios will crackle before the last beach towel is shaken free of sunset sand.
The mountains aren’t getting any lower, the sun isn’t getting any cooler, and the volunteers will still clock in on Monday - ready, again, to run uphill while the rest of the city sips its first flat white.
