Snow and ice are changing environments that make climbing challenging and exciting.
Mountaineers and sport climbers enjoy everything from moderate-angle walks up glaciers to
the vertical choreography of waterfall climbing — from volcanoes in the Pacific Northwest
to spectacular frozen waterfalls in the Rockies or the Northeast. Colorado, New Hampshire
and Banff, Canada see ice climbing activity in the winter months when features such as
Bridalveil Falls, Frankenstein Cliffs or Weeping Wall freeze up. The North Cascades of
Washington are often used as a training ground for climbing in the Andes or Himalayas
because of the variety of alpine snow and ice they offer.
This clinic focuses specifically on the techniques used on ice.
Getting Started Climbing Ice
Ice climbing typically brings to mind frozen waterfalls — a climber working his way up
vertical ice with 2 axes, crampons toe-in to the ice. Climbing alpine ice, though, can be
anything from walking flat-footed with crampons and a single ice axe to the twin-tool,
front-pointing scenario described above. A perennial glacier is a larger and more variable
beast than most winter waterfalls, so you need to use different techniques for changing ice
conditions and slope angles. First, we'll look at how you use your feet on the ice.
Crampon Techniques
Although it is possible to climb low-angle ice by using rough features or by chopping
steps with your ice axe, at a certain point crampons need to be used for efficiency, if not
safety. Alpine climbing involves techniques adapted to different terrain. These styles are
known as French and German technique, for the areas in which they originated. Modern alpine
climbing uses both of these styles.
-
French Technique— The French technique or flat-footing on ice is
the preferred technique for low-angle to moderately steep ice. All crampon points but
the very front are kept in contact with the ice for traction. This is the most efficient
way to travel over hard snow or ice. On lower-angle ice, climbing is simply a matter of
pointing your feet uphill and planting them solidly, including your heels. As the slope
angle increases, climbing requires greater ankle flexibility. It is easier to turn your
toes outward to walk ducklike in order to keep the feet flat. On steeper slopes, you can
progress diagonally up a slope with all points in, but with toes pointing across the
slope or even slightly downhill.
Eventually, it becomes necessary to sidestep up
the slope. To do this, plant your uphill foot solidly, then cross your lower foot
over it and plant solidly. This cross-over, upward progression requires care, as it
is easy to catch your crampon points on the opposite boot, gaiter or crampon straps.
It is important in the French technique to plant all points except the front two. It
is tempting to try to "edge" into a slope, placing only the inner row of points and
leaving the outer points in the air. This is easier on your ankles, but your crampons
can skate over the ice, allowing you to skate down the slope. The French
technique works on slopes up to about 40°. Beyond this, it's harder on the ankles,
and more advanced positions are required.
-
German Technique— The German technique is more commonly known as
front-pointing, due to the fact that only the front-facing crampon points come in
contact with the ice. It's commonly used on slopes of about 45° and up. The climber
faces the slope and kicks his toes in to plant the 2 or 4 front points. It is the most
direct way to ascend a steep slope but also the hardest on calf muscles since only the
crampon frames support your feet. Unlike French technique, which takes some practice to
get the footwork down, German technique is fairly straightforward. Kick, plant the front
points, stand. That's not to say that your foot placements shouldn't be precise. Your
body weight must rest on the few sharp points of your crampons and tools, so secure
footholds are essential.
-
Combined Technique— One way to make climbing moderately steep
ice more comfortable is to mix the German technique (or toe-in to the slope) with
flat-footing. This combination technique is known as the "3 o'clock position" or "pied
troisieme" and is usually less tiring than straight flat-footing. It involves planting
the front points of one foot while keeping the other foot splayed out to the side, sole
flat against the slope.
-
Some Style Pointers— It's common for beginners to kick
repeatedly to set the crampon points. This and kicking too hard are not only tiring, but
can weaken the ice you're standing on. You learn quickly enough about "dinner plates,"
or flakes of ice that come crashing out when you're too rough with tools or crampons!
Another tendency is to keep one's heels up too high, allowing the front points to pop
out. Lowering your heels leverages the front points farther into the ice. This is
especially important at the end of a steep section or a pitch that ends in a shelf or on
flatter terrain. As you top out, it's easy to let your heels come up as you reach and
climb over the edge. Working your feet higher and keeping heels low at this point will
help to avoid an unnecessary slip.
Walking on level or low-angle ice does not necessarily require the use of an ice axe. In
fact, it's a good idea to practice your flat-foot technique (with and without crampons)
without relying on your ice axe(s) so you learn the "feel" of the ice underfoot. Of course,
you carry and eventually use ice axes or tools on any ice climb. Longer mountaineering axes
are often paired with shorter ice tools on alpine routes which involve both snow and ice
travel. On steep, technical ice routes, 2 short tools are typically used, one with a hammer
and one with an adze. The adze is used for clearing the ice before placing ice screws or
for chopping steps or belay ledges. A hammer is used for pounding in ice pitons.
This section covers basics of using axes or ice tools on ice.
Ice Axe Techniques
- When placing your tools, look for depressions in the ice, which are stronger than
outward bulges and resist fracturing a bit better. If you are following, look for holes
left by your partner and place your tools in them.
- Just as with crampon placement, a single sure swing is far better than several taps or
random chops at the ice. It saves energy and the ice surface. The right amount of force
is important, too. Try to avoid swinging your tools too hard, or you will tire out your
arms quickly. The more you can align your shoulder, wrist and axe when you swing, the
more direct and secure the placement will be.
- To remove your tools as you climb past them, it's important to lift them out the way
they went in. Move the pick back and forth in the same direction it went into the ice,
and push up on the adze or hammer to help lift it out. Try not to wiggle the pick side
to side as this can break it.
Frequently ice routes are mixed with rock. Dry tooling is using your ice tools as
protection in cracks or other features on the rock. You can place the pick in a crack or
torque the hammer head into a rock feature and then work your way up with your tools as you
would if they were in ice. Some hammer-heads are even designed with different angles on
each side to fit into various-size cracks like a cam or chock.
Protection and Anchors on Ice
Just as with rock climbing, you need to place protection as you go to protect yourself
in case of a slip. Anchors allow you to belay your climbing partner and to rappel back down
from a climb. This section covers some of the tools and methods that ice climbers use for
protection.
Using Natural Anchors
Natural anchors can be used on an ice climb if you can find them. On waterfall ice, it
is common to find sturdy ice columns around which you can put a runner. On mixed climbs you
may find natural rock features such as horns to tie a runner around. Some ice climbers make
use of cracks between ice and rock by tying off an ice screw with webbing, placing it in
the crack and turning it 90° to create a chockstone.
Placing Ice screws
Ice screws must be placed in the ice securely, then clipped with a quickdraw to the
rope, all while you are standing on front points and hanging from 1 ice tool. It's a tricky
process for a beginner to master.
- You first need to clear away any rotten, soft ice or snow, until you reach good, solid
ice. Use your pick to create a small hole in which to start the screw.
- It should go in at about a 10° angle uphill from the direction of expected pull.
- Choose a spot in the ice near your waist rather than above your head for better
leverage while twisting it in. The pick of your free ice tool makes a good screwdriver
if you are having a hard time with just your hand.
- Newer ice screws with rotating handles make the process much easier!
- As you work the screw in, clear away any ice that fractures around it.
- Keep turning until the eye or hanger is flush with the ice surface and pointing
down-slope in the direction of pull.
- On very mushy or rotten ice, it's necessary to make a horizontal ledge in which to
place the screw. Place it vertically in the ice well back from the edge.
- Keep screw placements around 2 feet apart.
- Back up sketchy screw placements with second screws linked with runners and biners.
Ice Pitons
Pound-in protection is useful in certain situations where screws would fracture the ice.
Hook-style pitons can be placed in cracks, between ice features such as icicles or into old
tool placement holes. Use the hammer on your ice tool to pound them in.
Abalakov V-Thread
Named after the Soviet climber who first devised it in the 1930s, the Abalakov V-thread
anchor is simple in design, yet very strong. It's well suited to rappels or top-rope
setups, assuming that the ice in which it is made is of good quality.
- To make the anchor, you need two 22cm ice screws, a length of 7ml perlon or half-inch
webbing and a piece of wire to retrieve it.
- Insert the ice screws at a 10° angle uphill to the slope, and at about a 60° angle
sideways. The idea is to make tunnels with the 2 screws that meet in the middle.
- Leave the first screw partway in place as a marker for placing the second one.
- Once you have the tunnel, thread the perlon or half-inch webbing using a wire coat
hanger with a hook to retrieve it.
- Move the webbing or cord back and forth to smooth out the tunnel, then tie a knot to
create your anchor. If using webbing, use a water knot. For perlon, use a triple
fisherman's knot.
Ice Bollard
The ice bollard is another rappel anchor that is cut out of good-quality ice (that is,
hard ice with no cracks). It consists of a downward-pointing, teardrop-shaped trench in
which your climbing rope rests, with an upper lip that prevents the rope from sliding off.
- To make an ice bollard, use your axe's pick to make the initial shape, then the adze
for scooping out the trench.
- Cut out a trench at least 6 inches deep in the inverted teardrop shape, being careful
not to crack the ice.
- The bollard should be from about 1 foot to 18 inches wide. (Bollards are also used in
snow, but need to be much larger for the snow to hold.)
- At the top, make an undercut to keep the rope from slipping off. Be very careful not to
crack the horn shape that you've created for the rope to rest on.
These techniques of ice climbing are just the basics. For more in-depth information and
