# 055_Jackson_Dendron_legend

MATERIAL:
Neoglacial Till:stony diamiction, less then 1 m thick and in places discontinuous; end moraines (denoted by symbol) may be tens of metres thick and contain masses of buried glacial ice


MATERIAL:
Organic Deposits: peat and muck several meters to tens of metres thick; formed predominantly by the accumulation of vegetative material in bogs, fens and swamps in depressions and valley bottoms.  Permafrost is commonly present within 1 m of the surface in blanket bog: thermokarst collapse and palsa growth are common in bogs, fens, and swamps


MATERIAL:
Colluvial Deposits: stony diamicton resulting from the breakdown of bedrock through physical and chemical weathering; variably reworked and transported by gravitational processes such as creep, solifluction, debris flow, snow avalanching, and rockfall

DESCRIPTION:
bouldery diamicton, poorly sorted sands and gravels forming a wedge-like slope-toe complex of small steep debris flow and avalanche-dominated fans and solifluction deposits ranging from less then 1 m at the upslope limit to 10 m or more in the thickest part of the apron


DESCRIPTION:
bouldery, angular rockfall deposits that form aprons that may exceed 10 m in maximum thickness along the bases of steep slopes


MATERIAL:
Alluvial Deposits: gravel and sand with minor silt deposited by streams; deposits area commonly stratified and moderately to well sorted, except for some alluvial fan deposits where debris flow diamictons may be present

DESCRIPTION:
gravel and sand with minor silt, greater than 1 m thick, flat lying; includes lacustrine and organic sediments deposited in abandoned channels and backswamp areas; floodplain deposits subject to periodic inundation and reworking by floods


DESCRIPTION:
gravel and sand with minor silt, greater than 1 m thick; former floodplain sediments incised and now above the level of the contemporary floodplain; terrace sediments not subject to flooding and usually well drained


DESCRIPTION:
gravel, sand, silt, and diamicton up to 10 m or more thick; alluvial fans subject to stream avulsion and flooding and, on smaller and steeper fans, inundation by debris flows


DESCRIPTION:
floodplains, fans, and terraces that cannot be subdivided at this map scale


MATERIAL:
Glaciolacustrine Deposits: well stratified sand, silt, and clay deposited in lakes ponded by glacial ice;sediments may have regular surfaces or ridged, hummocky, or pitted surfaces caused by meltout of buried glacial ice.  Silts and clays commonly contain segregated ground ice and are affected by retrogressive thaw flow slides along rivers and contemporary thermokarst collapse

DESCRIPTION:
silt and fine sand, minor clay; 5 m or more thick


DESCRIPTION:
silt and fine sand, minor clay; 1 to 3 m thick but thin enough to conform to underlying topography


DESCRIPTION:
silt and fine sand, minor clay, less than 1 m thick or discontinuous


DESCRIPTION:
sand, silt, and clay; hummocky pitted, and ridged; may comprise 10 per cent or more gravel and diamicton lenses and dropstones, usually more than 5 m thick


MATERIAL:
Glaciofluvial Deposits: gravel, sand and minor silt, greater then 1 m thick, deposited by streams flowing from or in contact with glacial ice, including deltas graded to former glacial lake levels.  Sorting ranges from good to poor, and stratification from thin bedded to massive.  Sediments commonly display evidence of syndepositional collapse due to meltout of buried or supporting ice.

DESCRIPTION:
gravel, sand, and minor silt; planar surfaces, greater than 1 m thick


DESCRIPTION:
gravel, sand, and minor silt; planar surfaces cut by flights of terraces; greater than 1 m thick


DESCRIPTION:
sand, gravel, and minor silt and clay; commonly overlying lacustrine, silt and clay; greater than 5 m thick


DESCRIPTION:
sand, gravel, and minor silt and clay; greater then 5 m thick; forming kettles, esker and crevasse-fill ridges, includes minor elements of Gp and Gt


DESCRIPTION:
hummocky deposits of gravel, sand, and minor silt; less than 5 m thick; includes areas made up of 50 per cent units Mb and Mv


MATERIAL:
Morainal Deposits (till): diamicton, mainly till, generally consisting of a silty sandy matrix containing pebbles, cobbles, and minor boulders;  deposited either directly by glacial ice or by gravity flow from glacier ice

DESCRIPTION:
greater than 1 m thick but conforming to the underlying topography


DESCRIPTION:
less than 1 m thick or discontinuous, may contain extensive areas of thin (less then 1 m) and patchy colluvium


MATERIAL:
Bedrock: volcanic, sedimentary, metasedimentary rocks, and felsic and ultramafic intrusions; includes areas of thin colluvial cover, blockfield, sorted stone polygons in alpine areas.  R-A denotes bedrock subject to rockfall and snow avalanches.


DESCRIPTION:
flowing or stagnant glacial ice, locally covered by debris.  Also includes semi-permanent snow banks; thickness ranges from 10 m to tens of metres


LANDFORM:
Blanket bog or fen, generally <1 m thick


LANDFORM:
Bedrock subject to rockfall and snow avalanches
