Ice Climbing Grades: A Complete Guide

You should be aware of certain vital information before beginning a walk on ice or ice climbing. Is the path you intend to take as difficult or straightforward as climbing Mount Everest? Will you require tools to guide you? What would happen if you were to slip and fall? A climbing grade may be used to summarize several of these queries.

Climbers might expect certain things from the routes they choose to follow by using climbing grades, which are systems of letters or numbers. Without these rating systems, it would be challenging to predict how difficult a climb will be and whether or not you have the knowledge, courage, and skill necessary to complete it.

How Do Climbs Get Graded?

Because there are so many distinct climbing routes and locations, there are also a wide variety of grading systems in use. The ranking system for climbing routes, for instance, differs depending on whether they entail big rocks near the ground or ice far up in the mountains. While each grading scheme considers many elements, the majority assess one or more of the following:

  • Grading may be affected by sunlight. Rock climbs may be difficult to read in the light, whilst objects may be hidden from view in the shade. The position of the sun during the day can alter how tough a climb is. The overall state of the weather has a big impact since cold, dry conditions are often preferable to humid air or summer heat.
  • The climbing grade and climbing method are both impacted by the terrain. Peak limestone, for instance, is renowned for being “sticky damp,” or having the ideal temperature and humidity to make every grip seem absolutely firm.
  • Climbers first assess the route’s difficulty and contrast it with equivalent climbs before assigning a grade. They look at a huge wall’s angle, size, and quantity of grips, all of which are reasonably simple to determine. Other variables, such as rock friction, low angle slabs, direction to the sun, and the state of the route, are more complex and are best assessed while climbing.

However, how are these variables represented by a letter or a number? That’s the tough thing. The criteria used to evaluate a climbing route vary depending on the grading system. Routes receive grades depending on the author’s insights and experiences. They’re best guesses that came from considering only a few criteria, and they’re not intended to cover every scenario that could arise during a climb. In the following sections, we’ll go into greater depth regarding how these systems really assess climbs and the many rating systems in use.

The Grading System For Ice Climbing

Any track formed of ice is challenging to grade since ice is always changing due to melting, moving, expanding, and breaking. Additionally, an ice climbing route may have a different grade than it did in prior years since ice may vary from year to year. As a result, ice climbing grades primarily consider the ascent’s steepness and the level of technical proficiency needed. In the United States, climbing on three distinct forms of ice is graded according to three separate systems: water ice (WI), alpine ice (AI), and mixed ice (M).

Water Ice Grading System

Seasonal ice, or water ice (WI), is ice that melts away throughout the warmer months of the year. The water ice scale runs from WI1 to WI7.

  • WI1: Easy, low-angled ice. climbing on ice while using crampons.
  • WI 2: Water ice type II is average in size and has short bulges.
  • WI3: Long, steep bulges and sustained ascent with angles up to 70 degrees. There are many locations for screws and places to pause.
  • WI4: Constant ascent at 80o angles with some portions as steep as 90o and fewer rest stops.
  • WI5: Long and difficult climb with angles between 85° and 90° with limited rest stops or thin ice patches.
  • WI6: Long, 90-degree stretches of ice with no breaks and short pitches. These routes are rather complicated.
  • WI7: Long stretches of flimsy, poorly adhered ice with several challenges to overcome and lengthy 90o angles.

Alpine Ice

Alpine (AI) ice is persistent ice, similar to the ice often seen in glaciers at high altitudes. With the exception of the prefixes, the scale for alpine ice and the scale for water ice are identical (AI1-AI7 instead of W1-W7). The type of ice being graded is the main distinction between the two.

A route on Alpine Ice that has the same grade may be simpler to climb than one on Water Ice. But don’t be deceived; this is done to take into consideration that the alpine ice will be more difficult to get, farther away, and perhaps exposed to avalanche hazards. Alpine ice climbing is a unique activity, therefore just because the rating is lower doesn’t mean you should overlook it.

Mixed Ice

Routes that may have ice but also contain some rocks are known as mixed ice (M) routes. The Yosemite Decimal System and the mixed climbing scale have a strong relationship (YDS). Each grade on the mixed climbing scale, which goes from M1 to M13, is described in relation to a YDS rating. Mixed ice climbs can be graded using the International French Adjectival System because they also contain some rock (IFAS).

What Is The Point Of Climbing Grades?

Why do climbers develop grade systems and utilize them? When attempting a new route, climbers can gain a lot from being aware of and comprehending the knowledge acquired by earlier climbing groups.

Knowing the difficulty grade of a climbing route before trying is essential for climbers who wish to maintain control over their safety and manage risk.

The potential of harm when a lead climber fall exists even if contemporary sport climbing equipment and practices have made climbing far safer than it once would have been. The ability to predict a climbing route’s complexity is important for climbers who seek to reduce risk by reducing the likelihood of hazardous falls.

Climbers use climbing grades to monitor and compare their performance in mastering the sport. In order to motivate yourself to train harder and become stronger, you could create a climbing goal based on your capacity to complete a certain grade or route.

Ice climbing is a challenging and enjoyable pastime, but it requires much planning. Check the climb’s grade before starting it so you can decide if it’s appropriate for you to attempt it or if it may be preferable to choose an alternative path.
