Comme les glaciers sont souvent assez isolés, il est tout à fait possible de ne pas avoir de [[Commerce (trading)#Les caravanes |caravanes]] du "Mountainhome" pendant presque trois ans, et les migrants peuvent êtres plus rares même. Par contre cela s'applique aux [[Civilisation (civilization)|nations hostiles]] qui vous laisseront peut-être tranquille plus longtemps.

==Commencer sur un glacier==
  
Also, because of glaciers are often very isolated, it is entirely possible that you won't see a caravan from the Mountainhomes for anywhere up to 3 years. Migrants may be even more rare. On the plus side however, no hostile nations should bother you for a while.

== Starting on a Glacier ==
+
Selon le niveau de dépendence au commerce, les [[Bûcheron (wood cutter)|bûcherons]] peuvent êtres moins utiles sur un glacier, du moins jusqu'à la découverte des cavernes. Il est possible de le remplacer, ainsi que la hache, par un mineur avec une pioche. Sinon, si vous êtes <s>trop chochotte</s> à la recherche d'une expérience plus aisée, choisissez une carte où le glacier côtoie une forêt.
  
Take a lot of wood, food and drink. Consider bringing extra [[domestic animal]]s ([[dog|dogs]] are recommended, as are [[turkey|turkeys]] for their plentiful [[egg_production|egg yield]]) as an emergency food source, and/or to jump-start a long-term [[breeding]] program.
+
La [[Glace (ice)|glace]] est partout, renseignez-vous avant de trop planifier. Une différence entre la glace usuelle et celle de glacier; celle-ci, utilisée pour les constructions et ateliers ne fondra pas à l’extérieur, même en "été". Par contre il est plus difficile d'en obtenir de l'eau. Les blocs de glace obtenus en creusant, qui fondent une fois amenés à l'intérieur ne donneront '''pas''' d'eau (bug:360).
  
Depending on your level of trade dependency, wood cutters can have little use on a glacier. You may want to sacrifice your wood cutter and axe in favour of another miner and pick. However, be aware that wood is plentiful enough on glacial biomes if you can manage the caverns. Alternatively, if you're <s>a total wuss</s> looking for an easier experience, you can embark on a locale where a glacier overlaps a forested taiga to bolster your log supply.
+
===Creuser jusqu'à la roche===
  
[[Ice]] is everywhere, so read up on it before you make any major plans. One difference between regular ice and glacier ice that you may want to know before you head out is that, unlike ice from other biomes, glacier ice constructions and workshops do not melt when above ground in the "summer". The disadvantage, however, is that it is more difficult to use the ice as a potential water source. Note that mined out chunks of ice, when melted by being brought underground, will '''not''' produce usable water. {{Bug|360}}
+
À cause d'un bug, les [[Escalier (stairway)|escaliers]] vers le bas et ceux bas/haut ne peuvent êtres taillés dans la glace, si la couche immédiatement en dessous est rocheuse (bug:358). Il est donc impossible d'avoir un escalier creusé, de la surface jusqu'à la pierre. Pour pallier à ça construisez un escalier haut/bas avec la glace récoltée, à la place du dernier. Bien que ce ne sera pas une vraie couche de glace, elle ne fondra pas.
  
=== Digging down to the rock layers ===
+
===Culture et source d'eau===
  
Due to a bug, down-[[stair]]s and up-down-stairs can't be carved out of ice if the layer immediately below the ice is stone. {{Bug|358}} This makes it impossible to get from the surface down to the stone layers by purely digging stairs. The easiest way to circumvent this is to [[construction|construct]] an up-down staircase from some of the ice you will probably have mined out in the space where you intended to dig one. Despite being on a non-ice layer, the staircase will not melt.
+
Les glaciers n'ont pas de couche de [[Terre (soil)|terre]], il faudra irriguer ou cultiver dans les [[Caverne (cavern)|cavernes]]. L'eau est requise pour l'irrigation, ainsi qu'à l'[[Hôpital|hôpital]] pour les patients. Il y a deux façon d'obtenir de l'eau sur un glacier.
  
=== Farming and Getting Water ===
+
====Plans d'eau souterrains====
Since glaciers contain no [[soil]] layers you will either have to [[irrigation|irrigate]] or farm in caverns.  Water is required for the former approach, and is also needed at [[hospital]]s for cleaning and to give the wounded something to drink.  There are two ways to get water on a glacier.
 
  
==== Underground Pools ====
+
Toutes les régions du monde ont de vastes cavernes souterraines, à moins qu'il n'est été [[Création d'un Monde (World Generation)|généré]] sans, et elles ont très souvent des lacs. Si ce lac touche la bordure de la carte locale, il sera automatiquement approvisionné en eau, à l'infini. Par contre atteindre les cavernes peut prendre du temps, creuser directement à la verticale ne garantit pas de les trouver, et ils peut y avoir de drôles de bestioles qui traînent par là.
All regions of the world have vast underground [[caverns]] (unless the world was [[world generation|generated]] without them), and caverns almost always have large pools of water. Further, if the pool abuts the edge of your embark area, new water will fill in from the edge, giving you an infinite source of water. On the down side, it can take a while to find the caverns, since digging straight down isn't guaranteed to breach them, and there's a small chance of aquatic monsters escaping from the cavern, or worse, not being able to find any water.
 
  
The "quick-and-dirty" approach that springs to mind for this is to simply dig one z-level above the water and build a well, but beware that aquatic beasts can and will climb into your fortress through your well. The approach below allows for a safe, sealed off reservoir.
+
On peut creuser un trou un niveau au-dessus, et y mettre un [[Puits (well)|puits]], mais certaines créatures pourront quand même passer par là.
  
To safely (without having to wander around inside the cavern) tap into an underground pool, consider the following diagram:

Les glaciers sont des biomes extrêmement froids, aux extrêmes nord et sud sur les grandes cartes. Les premières couches d'un glacier sont de la glace.

Il y a peu de ressources sur une case de glace; pas d'arbres, d'animaux, de pierres, d'eau, de minerai. En plus la glace peut avoir plusieurs niveaux Z d'épaisseur.

Le manque de terre sur un glacier associé aux températures glaciale empêche l'agriculture. Ce qui veut dire qu'il sera impossible d'y faire pousser les plants de surface. Le choix se limite donc aux plantes souterraines.

Ces facteurs font qu'un glacier est un endroit rude pour fonder une forteresse, bien que beaucoup aiment la difficulté qu'il présente et s'y essayent.

Comme les glaciers sont souvent assez isolés, il est tout à fait possible de ne pas avoir de caravanes du "Mountainhome" pendant presque trois ans, et les migrants peuvent êtres plus rares même. Par contre cela s'applique aux nations hostiles qui vous laisseront peut-être tranquille plus longtemps.

Commencer sur un glacier

Prenez beaucoup de nourriture, de boisson et de bois. Quelques animaux domestiques; des chiens, des dindons pour les oeufs. Ils peuvent servir de nourriture en cas d'urgence, et/ou pour démarrer un élevage.

Selon le niveau de dépendence au commerce, les bûcherons peuvent êtres moins utiles sur un glacier, du moins jusqu'à la découverte des cavernes. Il est possible de le remplacer, ainsi que la hache, par un mineur avec une pioche. Sinon, si vous êtes trop chochotte à la recherche d'une expérience plus aisée, choisissez une carte où le glacier côtoie une forêt.

La glace est partout, renseignez-vous avant de trop planifier. Une différence entre la glace usuelle et celle de glacier; celle-ci, utilisée pour les constructions et ateliers ne fondra pas à l’extérieur, même en "été". Par contre il est plus difficile d'en obtenir de l'eau. Les blocs de glace obtenus en creusant, qui fondent une fois amenés à l'intérieur ne donneront pas d'eau (bug:360).

Creuser jusqu'à la roche

À cause d'un bug, les escaliers vers le bas et ceux bas/haut ne peuvent êtres taillés dans la glace, si la couche immédiatement en dessous est rocheuse (bug:358). Il est donc impossible d'avoir un escalier creusé, de la surface jusqu'à la pierre. Pour pallier à ça construisez un escalier haut/bas avec la glace récoltée, à la place du dernier. Bien que ce ne sera pas une vraie couche de glace, elle ne fondra pas.

Culture et source d'eau

Les glaciers n'ont pas de couche de terre, il faudra irriguer ou cultiver dans les cavernes. L'eau est requise pour l'irrigation, ainsi qu'à l'hôpital pour les patients. Il y a deux façon d'obtenir de l'eau sur un glacier.

Plans d'eau souterrains

Toutes les régions du monde ont de vastes cavernes souterraines, à moins qu'il n'est été généré sans, et elles ont très souvent des lacs. Si ce lac touche la bordure de la carte locale, il sera automatiquement approvisionné en eau, à l'infini. Par contre atteindre les cavernes peut prendre du temps, creuser directement à la verticale ne garantit pas de les trouver, et ils peut y avoir de drôles de bestioles qui traînent par là.

On peut creuser un trou un niveau au-dessus, et y mettre un puits, mais certaines créatures pourront quand même passer par là.

Voici une méthode pour un réservoir sécurisé, sans avoir besoin de se balader dans les cavernes, vue du dessus:

Puis faites ceci:


  1. Dig down to the same level as the pool (not to the surface of the pool) and dig out the reservoir (rectangular region) with stairs (or ramp) leading out.
  2. If you're going to use the reservoir for irrigation then dig an outlet from the reservoir at the F, install a floodgate at its mouth, and hook it up to a lever.
  3. Dig a tunnel to the pool, leaving one tile's worth of stone between the tunnel and the water (the X in the diagram).
  4. Install a floodgate or a south-raising drawbridge at the end of the tunnel and hook it up to a lever.
  5. Have a dwarf dig out the X.

The dwarf who dug the X should be able to get back to the stairs/ramp in time to not drown. To make extra sure of not drowning, ensure at least one dwarf is idling and have him/her pull the lever to the floodgate/drawbridge as soon as the wall is breached, then lower it again to let the reservoir fill. To make extra, extra sure, embark with a dwarf with a single point in the swimming skill, and have him/her carve the fortification.

Use a drawbridge instead of a floodgate at the end of the tunnel to prevent building destroyer aquatic/amphibious monsters from swimming into the reservoir and enter the rest of your fortress. A floodgate wouldn't stop a building destroyer, and monsters can swim through fully submerged fortifications.

Bug signalé !  

{{{description}}}


 If you're going to use this reservoir for a well then closing off it off with a drawbridge is very important, since some building destroyers can swim and fly.  If you're only going to use it for irrigation then you can use a floodgate and then simply wall off the reservoir once you're done with it, since building destroyers can't affect walls.

If you're going to use the reservoir for a well you should cover its floor with a paved road to prevent trees from growing, because in some circumstances trees can grow underwater.

Dwarven Ice Cutting

This may not work, beware.

One quirk of dwarven physics is that a cave-in will transform an ice wall into liquid water. This can be used to generate water in the following fashion:

To begin, it is best to clear out a large section of the rock underneath all the ice. Then cut out a 6x6 section of ice (it is easiest to cut out two squares around the part you want to drop so that you won't have any fatalities while channeling out the section of ice). Channel out the entire piece of ice and it will fall into that cleared out section, immediately defrosting and flooding the area. Now you can farm!

Before you run out of starting booze, do the same again, but this time do it further away and open 3-4 levels of rock (channel everything away) so that you create a well. Make sure you make it deep enough or you will create an ice zone that will kill any dwarf that tries to dig it out.

Continue to cut out chunks of ice, dropping them a few stories, and reaping the benefits as you continue in the fortress. Be careful channeling as the dwarves are all idiots and like to strand themselves while channeling, and they like to drop their buddies down the hole (which pollutes the future water and creates a huge mess).

Diagram of Ice cutting:

Modèle:Diagram

O = Open area, no channeling, just an area for dwarves to walk

C = Channel area, first dig it out, then channel once every layer is ready.

I = Future water source, now ice.

Once you have dug deep enough to see rock, channel out the entire level (make sure you have an escape route for the miner). Also, when channeling a large room, do it layer by layer. Start at the one end and do the entire left side, then the next. If you just select the entire thing dwarves will die.

Don't drop water anywhere near other tunnels; the ice will break through, and it will be messy. You can cut off entire sections of fortress to flooding or caved-in sections by doing this, and it wastes a lot of work and ice.

Other Approaches

Aquifers are sometimes present on glaciers, and magma can be used to melt ice (although the only reliable source of that is very deep underground). Seaside glaciers can allow you to bring some water in underground, but desalinating the water will be necessary before it is drinkable by dwarves (or even before it can be designated as a water zone for filling ponds).

Beware that flowing sources of water, such as rivers or brooks, don't ever seem to be present in glacier biomes.

Trade

Trade on glaciers is an issue of contention for some glacial Dwarf Fortress players.

Some players argue that trade is basically essential on a glacial biome. Anyone playing on a glacier will inevitably end up with a lot of rock, so a commonly suggested source of income is rock crafts. However, beware that ice cannot be used to make crafts, even if the craftdwarf's workshop is on a z-level with freezing temperatures that would keep the ice from melting. The majority of your imports will be wood, used for making beds and other necessities, as well as fuel for making metal objects.

However, also be aware that independence from trade on a glacial biome is entirely possible. It does require extra effort and careful rationing of certain materials, but it can be done.

Glacial Independence

Gaining independence from trade on a glacier is a difficult prospect, primarily because of the lack of wood to be found on glacial biomes. However, even though wood is commonly used in the creation of various constructions and tools, it is almost entirely replaceable with either stone or metal crafting. However, there are two wood-based needs in Dwarf Fortress that are trickier to circumvent: beds and fuel.

Beds

The need for wood in the construction of beds is unavoidable: no other material in the game can be used to make them. However, that is not to say that trade is the only thing that can supply wood. The answer here lies in caverns. Caverns grow trees on their soil constantly, and if correctly managed, can be turned into tree farms. However, the trade-off is that to supply wood for beds early, aggressive expansion into the caverns will be required, which can be extremely fun. In light of this, it is recommended to bring at least seven logs with you on embark to build beds for your first seven dwarves, and to read up on caverns and their dastardly, dangerous darting denizens.

Fuel

Fuel is a different matter; wood does not have to play a part in its production. If you are very lucky, you may find bituminous coal or lignite, the two stones which can be turned into fuel for metalwork, but the odds are that you will have to do without. For this, your best option is to get down to the magma sea as soon as you can to build magma-based smelters, forges and the like, or at least as soon as you need to start using metal. This has the added advantage of quite possibly leading you to discover additional caverns (and thus sources of wood and water) along the way.

Needless to say, read up on magma before attempting this. Magma's usage can lead to an awful lot of unexpected fun in inexperienced hands. Also take a look at the various other hazards that can confront anyone working with the magma sea, and consider channelling some of the sea into a reservoir or using a pump to isolate your working dwarves from them. Once you have got the hang of it, magma really is a blessing because of its lack of limitations; the magma sea is not about to "run out" of magma, and it also makes for good hippie garbage disposal. Also, if you are very lucky indeed, you may well stumble across something special.

Wildlife

Notes

Ice that is underground melts, but creates only useless puddles of water (marked as a cyan double tilde) identical to water dumped from a bucket. These puddles can only be cleaned. They cannot form usable water (blue tilde with depth attribute). Dumping block after block of mined ice blocks indoors will simply result in a huge stack of useless "water".

Glaciers are very unlikely to have a source of shells. Thus, you may want to mod the game so that some other material can be used in place of shells for the occasional strange moods which call for them; see Shell for details.

Some glacier biomes have such low temperatures that your dwarves and animals may die if exposed aboveground for too long.

Water in buckets does not freeze above ground so you can designate an area as a pool, tell dwarfs to fill it, then smooth and engrave your new ice fort.

Volcanoes and Glaciers

If you embark on a Glacier Biome with a Volcano you might think it would be a good idea to erupt the volcano (dig a hole into its side) onto the glacier ice. This will indeed cause some interesting effects like multiplying the amount of ice, casting obsidian and spamming you with cavern" collapsed" messages. The ice will expand due to the fact that one molten wall of ice will become 7 units of water, potentially flowing apart in all directions and freezing into new walls of ice immediately, which can then melt into 7 more units of water. If the water flows to the same square as the magma it will turn to obsidian. Both the ice and the obsidian walls may not be connected to another solid wall so a lot of cave-ins will occour.
