This feature article was snagged from Crampons can be divided into five categories according to
the type of terrain they are designed for: waterfall ice;
general mountaineering; technical alpine ice; trekking/hiking;
and ski mountaineering. It’s hard to get one pair of crampons that perform
acceptably in multiple situations, so a candid assessment of
what you are likely to be doing is key. Bear in mind, however,
that a good general mountaineering crampon will do a better
job on waterfall ice than a waterfall ice crampon will do in
the mountains! This is because of the great tendency of
waterfall crampons to "ball up" when walking on snow, creating
a platform of snow on the bottom of the crampon that destroys
all traction and balance. Balled up crampons are dangerous and
a pain in the butt, as you find yourself continually whacking
your crampons with your ice axe. For women, it may be desirable to avoid crampons that have
a wide spread between the front points. Climbers with small
feet are able to be precise in their foot placements. If the
front points are too far off to the side, it is harder to be
precise. The smaller the boot, the more pronounced the
difference. Similarly, the length of the crampon teeth can
make a difference. The longer the teeth, the further your foot
is from the ice, snow or rock surface relative to your size
and weight. With a small boot, this distance can make a
difference in how stable your foot placements feel, especially
when you are on rock. While shorter teeth will help with
precision and reduce fatigue slightly, they may also wear out
faster. Crampons for Waterfall Ice Good crampons for waterfall ice climbing are usually among
the heaviest. They have a front bail and heel lever. They
typically have vertically oriented front points, which shatter
the ice less and provide better purchase on hard ice.
(However, a beefy, rigid crampon with horizontal points works
pretty well on waterfall ice, too.) The crampon frame is
vertically oriented for rigidity and support to the boot sole.
Some models have interchangeable mono- and dual- front points.
Mono points are useful for mixed climbing and on good, clean,
hard ice. They tend to feel a little less stable until you get
used to them, but allow more freedom of body position.
Interchangeable points give you both options. General Mountaineering Crampons General mountaineering crampons have horizontally oriented
front points to hold better on snow and the soft, sun-eroded
surface ice of glaciers. They have variable types of straps or
systems to attach them to a wide variety of boots. Look for a horizontal (flat) frame orientation to prevent
balling-up on snow. (Some manufacturers make customized
anti-bottes (anti-balling up devices) to fit their crampons,
which are a good investment.) Buy the lightest weight crampon
that you can for the degree of technical difficulty you will
undertake. If you want to use your crampons with a boot that
doesn’t have a groove in the toe for a front bail, look for a
good attachment system that has a strap on the toe combined
with a heel lever in the back. If your boots don’t have much
shelf in the back or are really flexible, you may need a strap
attachment in the back as well. Technical Alpine Crampons These crampons are a subset of general mountaineering
crampons, but they have some slight differences to improve
technical performance on more difficult ice or mixed climbing.
Typical characteristics of technical alpine crampons include
slightly heavier weight, second points that are more raked
forward to help with ice climbing (but can be a hindrance on
rock), and longer points. Some of these crampons are rigid,
unlike general mountaineering crampons. They usually have a
front bail attachment system since it is assumed that they
will be used with technical boots. Hiking/Trekking Crampons The main purpose of these crampons is to provide security
on the odd snow or ice section during an otherwise hiking or
scrambling route. They are made to fit the lighter more
flexible shoes and boots that would be appropriate on such
routes. Because the need for crampons is incidental, you can
get away with a much lighter weight, less technical crampon,
and the weight of the crampon becomes much more important
compared to other features. Crampons in this category can be
very good even for major glaciated climbs like Ranier or Mont
Blanc, where there is a lot of snow and ice but little
technical difficulty. Typical features of a hiking crampon include strapping and
attachment systems that fit a variety of boots, light weight
(sometimes achieved by having less than 12 points), shorter
points, and a flat, non-rigid frame. These crampons are quite
specialized, but if you contemplate a lot of off-trail travel
on non-technical ground where snow and ice have to be crossed,
the light weight of these crampons is worth a great deal. Ski Mountaineering Crampons Designed to be used on ski tours that take in sections of
terrain where steep or hard snow makes skiing impractical,
these crampons must be lightweight. The crampons are used only
occasionally, and should not contribute much weight to your
overall load. The best models are made of aluminum. The front
bale must be sized to fit standard DIN toes on ski and ski
mountaineering boots. These again are quite specialized, but
if you are an occasional non-technical crampon user they are
ideal. More questions? question@mountainwoman.com Go to Tools |
