5a

5c

Siempre caminar en la nieve con un acompañante.

5d

Tener agua y alimentos suficientes.

5e

Tener un botiquín de primeros auxilios un kit de supervivencia y de reparación.

First Aid Kit

A minor injury, if left untreated, can become life threatening in the wilderness. Bring a first aid kit to keep a minor injury minor.

Survival Kit

A survival kit will contain items to prevent death by exposure. It should include reliable fire-starting equipment, a whistle, and an emergency blanket or sleeping bag. Spare, dry clothing is also a good idea.

Repair Kit

A repair kit will help you to effect a repair to a broken snowshoe or to a torn item of clothing. Duct tape and cable ties can work miracles. Remember that snowshoes will allow you to travel farther faster, so if you get halfway through your journey and your snowshoes fail, you will have to execute the second half without the benefits a snowshoe provides. This translates into slower progress, potentially leaving you in the wilderness after darkness falls, and exposing you to additional risk. Compromised outerwear will not keep water away from your skin, so it too should be repaired in the field if necessary.

Con un par de raquetas de nieve, demostrar cómo levantarse después de haber caído en la nieve.

The first thing to do when you fall is to check that you are not injured. Then roll onto your stomach, raise yourself up on all fours, pushing with your forearm until you can shift your weight to your knees. Assume a kneeling position. Then while steadying yourself with trekking poles (if you are using them), raise one knee and get the snowshoe beneath yourself. Then as you stand on that leg, get the other shoe into its proper position.

Once you have regained your feet, brush as much snow off yourself as you can. Otherwise, it will melt on your clothing and you will get soaked. Remember that the secret to staying warm is to stay dry.

Demostrar la importancia de colocar correctamente las raquetas a las botas.

When traditional wooden shoes were still popular, it was common to buy the bindings separately (much like downhill skis), and many wooden shoes are still sold this way). They were commonly called "H" bindings, since they consisted of a strap around the heel crossing a strap around the toe and one at the instep, forming a rough version of that letter.

On modern shoes, there are two styles of binding: fixed-rotation (also known as "limited-rotation") bindings, and full-rotation (also known as "pivot") bindings. With either binding system, the heel is left free, and the difference is in how the ball of the foot is attached to the snowshoe.

In fixed-rotation bindings, the binding is attached to the snowshoe with an elastic strap that brings the tail of the snowshoe up with each step. The snowshoe therefore moves with the foot and the tail does not drag. Fixed-rotation bindings are preferred for racing. Full-rotation bindings allow the user's toes to pivot below the deck of the snowshoe. They allow the crampon cleats that are under the foot to be kicked into a slope for grip in climbing, but are relatively awkward for stepping sideways and backwards as the tail of the snowshoe can drag. Fixed-rotation bindings often cause snow to be kicked up the back of the wearer's legs; this does not tend to happen with full-rotation bindings.

A series of straps, usually three, are used to fasten the foot to the snowshoe. Some styles of binding use a cup for the toe. It is important that a user be able to manipulate these straps easily, as removing or securing the foot often must be done outdoors in cold weather with bare hands, exposing him or her to the possibility of frostbite. When putting on snowshoes, left is distinguished from right by which way the loose ends of the binding straps point: always outward, to avoid stepping on them repeatedly.

In 1994, Bill Torres and a younger associate developed the step-in binding, designed to make it easier for snowshoers wearing hard-shelled plastic boots (serious mountaineers) to change from snowshoes to crampons and back again as needed.

Snowshoe manufacturers each have their own designs for bindings, and each design fastens differently. Because of this, it is not possible to give generic instructions for fastening them. You will have to consult the instructions that come with your shoes in order to fasten them correctly.

When selecting snowshoes, the bindings are one of the most important features to consider. They should be easy to put on, and easy to get off. If they are not, you will be much less likely to use them. Also remember that the bindings will likely require adjustments while you are out on the trail. Under these conditions, the straps are likely to be stiff with ice, and your fingers are likely to be cold.

Some experienced snowshoers advise against bindings that are based on straps that make two passes through a buckle and rely on friction to stay put.

Participar en una serie de tres caminatas: una corta, una de 1 milla (1.5 km) y una de 2 millas (3.2 km). Hacer un informe detallado que describa la profundidad y las condiciones de la nieve, plantas y animales, y la velocidad aproximada de sus pasos.

An excellent place to begin snowshoeing is on a golf course. The course will obviously not be used by golfers when it is covered with snow. Golf courses provide open spaces and gentle slopes. Other options are parks, hiking trails, and cross-country skiing trails.

Be sure to record your trip as soon as possible upon your return. It is easy to forget details. Measure the snow depth with a stick. Is the snow light and fluffy, or is it wet and packed?

To maximize your chances of seeing wild animals, minimize your noise. Look for animal tracks and listen for birds. Bring a camera and see if you can capture the beauty of the snow-laden landscape.

Explicar el significado de la expresión «más blanco que la nieve» que se encuentra en el Salmo 51:7. ¿Qué otras metáforas se pueden utilizar para explicar el significado de este versículo?

Cleanse me with hyssop, and I will be clean;
wash me, and I will be whiter than snow.
-- Psalm 51:7 (NIV)

The color white represents purity. In this verse, the psalmist compares sinlessness with the whiteness of snow. It is easy to see flecks of dirt in snow, and it is likewise easy to tell that snow is clean and pure. When we are cleansed of sin by Jesus, we are completely purified.

For other metaphors, try to think of things in nature that are pure or white. Here are some ideas:

• Rain water
• Wool
• Flour
• Pure grape juice (wine has leavening in it, and leaven is a symbol of sin).
