SANDSTONE, MINN. — A variety of soft thunks can be heard in between hollers of encouragement as more than a dozen climbers — mostly college-aged — take on a giant wall of ice for the first time.
They tip their helmeted heads to stare up the rippling formations that look gray or white in the shade, but glow with blues and yellows when the sun shines on Sandstone's Robinson Quarry, also known as the Robinson or Sandstone Ice Park.
It takes practice to "read" the ice and gauge the most stable spot to thrust in spiked crampons attached to sturdy boots. Thunk. Then there's the higher pitched sound of an ice ax picked into the ice. It helps to have a good ear, too.
"When you get a good stick, it's going to sound different," coached Bryan Karban of Vertical Endeavors, who was leading this group of novices a couple weekends ago. "It's all in the flick of the wrist," he continued. "And learning to trust your feet is the biggest challenge."
Ice climbing requires balance, plus skills in transferring weight, choosing good ice and leveraging strength while simultaneously being aware of how winter affects the muscles. If you keep your arms continually elevated during a climb in cold temperatures, it's going to be a wicked rush of blood when you finally bring your arms down. Karban said climbers have dubbed that experience "the screaming barfies" for the urge to throw up from the pain.
Safety is essential — including gear such as helmets to protect against falling ice or falling gear. It's one of many reasons to learn this tricky sport from the experts.
Given the cost of ice-climbing equipment — which can easily run upward of $1,000 for boots, crampons, axes and ropes, webbing and harnesses — it's doubly wise to try ice climbing first with a guide or an outfitter. An even better way to get introduced to the sport comes next weekend with the 10th annual Sandstone Ice Festival.
Both beginners and experienced climbers will have the opportunity to test out equipment while participating in a variety of ice-climbing clinics and talks. It's also a good chance to learn about winter camping.
