WETLAND_SURFACE_FORM |
DOMED_BOG |
A large <BOG> (<<OUTSIDE_DIAMETER>> usually greater than 500 metres) with a convex <SURFACE> rising several metres above the surrounding <LAND>; domed bog. The centre usually drains in all <DIRECTION>s, and small crescentic pools commonly form around the highest point. A concentric pattern is formed if the highest point is in the centre, while an eccentric pattern is formed if the highest point is off-centre. Peat development is usually greater than 3 metres deep. |

WETLAND_SURFACE_FORM |
POLYGONAL_PEAT_PLATEAU- _BOG |
A perennially frozen <BOG> rising approximately 1 metre above the surrounding fen; polygonal peat plateau bog. The <SURFACE> is relatively flat, scored by a polygonal pattern of <TRENCH>s that developed over wedges of <ICE>. The permafrost and wedges of <ICE> developed in peat originally deposited in a non-permafrost environment. |

WETLAND_SURFACE_FORM |
PEAT_PLATEAU_BOG |
A <BOG> composed of perennially frozen peat rising abruptly about 1 metre from the surrounding unfrozen fen; peat plateau bog. The <SURFACE> is relatively flat and even, and commonly covers large areas. The peat was originally deposited in a non-permafrost environment and is associated in many places with collapse scar <BOG>s or fens. |

ATLANTIC_PLATEAU_BOG |
A <BOG> with a flat to undulating <SURFACE> raised above the surrounding <LAND>; Atlantic plateau bog. The edges of the <BOG> commonly slope steeply downwards to the mineral soil <LAND>. Large pools scattered on the <BOG> reach depths of 2 to 4 metres. |

WETLAND_SURFACE_FORM |
BASIN_BOG |
A <BOG> situated in a basin with essentially closed drainage that receives <WATER> from <PRECIPITATION> and <RUN_OFF> from the immediate surroundings; basin bog. The <SURFACE> of the <BOG> is flat with peat generally deepest at the centre. |

FLAT_BOG |
A <BOG> having a flat, featureless <SURFACE> and occurring in broad, poorly defined <TERRAIN_DEPRESSION>s; flat bog. The depth of peat is generally uniform. |

WETLAND_SURFACE_FORM |
SLOPE_BOG |
A <BOG> occurring in areas of high rainfall on appreciably sloping land <SURFACE>s. The <BOG> is fed by rainwater and by water draining from other nutrient-poor peat lands. The peat may exceed 1 metre in <<THICKNESS>>. |

VENEER_BOG |
A <BOG> occurring on gently sloping <LAND> underlain by generally discontinuous <PERMAFROST>; veneer bog. Although drainage is predominantly below the <SURFACE>, overland flow occurs in poorly defined drain ways during peak <RUN_OFF>. Peat <<THICKNESS>> is usually less than 1,5 metres. |

LOWLAND_POLYGON_BOG |
A <BOG> with flat-topped or convex peat <SURFACE>s (often referred to as "high-centre polygons") separated by <TRENCH>s over wedges of <ICE> that form a polygonal pattern when viewed from above; lowland polygon bog. The peat was deposited in a permafrost environment as shown by internal structures. |
