Ice Poles & Ice Pikes
Why Ice Poles?
Of all the specialized gear items available to Nordic ice skaters, ice poles and pikes are the most important. They’re the ‘ounce of prevention’ that keeps us from falling through the ice. They’re the ‘magic wands’ that allow us to navigate safely through a maze of thick and thin ice without making a misstep.
An ice pole looks a lot like a ski pole that’s missing a basket. A wooden ice pike, on the other hand, has its own unique appearance. Examples are in the photo on the right.
Upon closer inspection you’ll notice a few more differences:
(a) An ice pole has a hardened steel tip designed for penetrating ice. Unlike a ski pole, an ice pole or pike won’t slip on hard, smooth ice.
(b) An ice pole shaft is made of aluminum (or wood), not fiberglass or carbon fiber, so it can withstand the impact of stabbing it into the ice with all your strength.
(c) There’s no wrist strap, so you can toss your ice pole aside if you start to fall.
How do you test the ice?
The basic test is to hold the pole a safe distance away from your feet, raise it above your shoulder, and then stab it straight down into the ice with all your strength. You must stab it straight down, not at an angle, to get an accurate result. Then, if you’ve never used an ice pole before, you’ll need to ‘calibrate’ your pole based on your body weight, arm strength, and the experience of other skaters.
For example, I weigh 155 lbs. and I think I have a pretty strong arm. I can penetrate two inches of hard black ice with a single poke. I call this ‘one-poke ice’ and I avoid it, because it tends to make disconcerting cracking noises underfoot and it just doesn’t give me enough of a safety margin. On the other hand, maybe you can penetrate three inches, or maybe just an inch. The only way to find out is if we both poke the same ice and compare our results.
The number of pokes needed to penetrate cold (sub-freezing) black ice and hit the water underneath goes up exponentially as the ice thickens.
Here’s an approximate table based on my arm strength. You’ll need to adjust the numbers based on your arm strength.
1 poke = 2 inches of black ice at subfreezing temps
2 pokes = 2.5 inches
4 pokes = 3 inches
8 pokes = 3.5 inches
16 pokes = 4 inches
32 pokes = 4.5 inches (my shoulder is aching before I get to this point)
Gray ice
Gray and white ice are much softer than black ice, because of their higher air bubble content. And gray ice usually consists of multiple layers of varying densities. It’s impossible to gauge the thickness of gray ice by counting pokes, so all you’ll get is a measurement of ice strength relative to X number of inches of black ice. And since you can’t see into the ice, it’s hard to know where to poke aggressively, and where to take it easy. Unless you’ve been observing the lake all winter long and you already know where the thicker and thinner areas are, you’ll have to poke the entire lake to feel safe. There may be a foot of ice at one end of the lake, and only an inch of ice at the other end, but your ice pole will help you tell the difference.
Sandwich ice
Ice poles and pikes are useful for probing ‘sandwich ice’ - a layer of water or slush trapped between two layers of ice. If you poke and hit a solid subsurface ice layer, but water oozes up through the hole you’ve made, chances are you’ve penetrated a trapped layer of water or slush. Sandwich ice can be a serious trip-and-fall hazard, so proceed with caution, or turn around.
Ice Poles vs. Ice Pikes: Pros and cons
It was February 1999. I was skating on Lake Mälaren in Sweden with my Dutch friend Arjen. Two Swedish skaters, Kristian and Ylva, appeared in the distance traveling in the opposite direction, and as if we all felt the pull of some magnetic field, our paths converged.
I took a group photo (right). It was a study in contrasts, and I’m not just talking about wardrobes. Their skates ranged from Ylva’s ancient wooden skates with crisscrossed leather straps (center), to Kristian’s ‘modern’ aluminum-deck skates matched up with leather telemark boots (left), to Arjen’s ‘ultramodern’ Salomon skate boots and Nordic skates (right).
But what about their poles? Why was Kristian carrying just one pole instead of two? And why was his one pole so big, tall and heavy?
Centuries ago, when skate blades were made of animal bones instead of steel (which hadn’t been invented yet), and they had no edges to push off with, the only means of propulsion was a stout wooden ‘pike’ with a forged iron tip, with which you pushed backwards to propel yourself forward. The iron tip could also be used to test the strength of the ice.
Nowadays we have access to modern materials. A pair of ice poles with ergonomic grips, aluminum shafts and hardened steel tips is not only lighter in weight than a single ice pike - but also much more versatile.
You can test the ice with either a pike or a pole. But look at all the things you can do with a pair of ice poles that you just can’t do with an ice pike:
1. Keeping your balance and momentum on bumpy or snow-covered ice
2. Skating into a headwind
3. Double-poling across ice that has become too soft to skate on
4. Keeping your balance sidestepping a pressure ridge or an open crack
5. Crossing jumbled chunks of 'pack ice'
6. Getting an upper-body workout instead of letting your arms hang useless
7. If you break a skate, double-poling back to shore, gliding on your one remaining usable skate and using your poles like crutshces
And here are the advantages of an ice pike:
1. It makes you look traditional, ‘old school’.
2. It’s heavier, so it gives you more ‘oomph’ when stabbing the ice - unless your hand slips on impact.
3. If made from a carefully selected piece of wood, it’s a work of art.
What length poles to get?
I recommend sizing ice poles like back country ski poles. They should come up into your armpits but no higher. This will give you plenty of length for keeping your balance and pushing yourself along. Shorter poles also weigh less and have a lower ‘swing weight’. Most importantly, if you need to test the ice, a short pole is just easier to thrust straight down into the ice without having to lift it over your head. Here’s my pole sizing chart (personal preference may vary):
5’0” and shorter - custom lengths up to 120cm
5'1" to 5’4” - 125cm
5'5" to 5'8" - 135cm
5'9" to 6'0" - 145cm
6'1" and taller - 155cm
I'm 5'10". I use 160cm skate-skiing poles and 150cm classic ski poles. But for ice skating, I use 145cm poles. I also tried 135’s and 155's but they didn’t feel right.
My wife is 5'3" and a former cross-country ski racer. She uses 145cm
skate-ski poles and 135cm classic poles. But for ice skating, I customized a pair of 125's for her.
These are just my suggestions. If a 5'4" skater uses 135's instead of 125's, it's not a disaster. But longer poles are heavier, with significant swing weight thanks to the big steel tips.
My favorite ice testing poles are made in Sweden by Skyllermarks. (See photos at right.) Their grips are specifically designed for ice testing, while other manufacturers just use generic ski-pole grips.
