|1||Landtype Association||This indicates the LTA that the ecological land type
is in. Within the north half of the GMNF one of the following:
0 - High elevation
1- West side of mountains
2 - East side of mountains
3 - Northeast portion of the National forest, unique soil mineralogy
|2 and 3||Geomorphic Process||Within the north half of the GMNF, one of the following
two digit codes indicating the dominant glacial or periglacial geomorphic
02 - subglacial scouring (shallow tills)
03 - subglacial deposition (basal tills)
05 - superglacial deposition (ablation tills)
10 - glacial outwash
11 - slack water deposition
13 - subglacial scouring and subglacial deposition in subalpine climatic zones above 2500'
14 - soils subjected to repeated freeze-thaw cycles in alpine climatic zones above 3000'
|4||Modifer||One of four letters that further defines the ELT:
a - wet soils that are permanently or seasonally saturated
b - shallow soils, typically less than 5' to bedrock
c - units that are dissected by numerous intermittent streams
d - typical or modal conditions; unit fits the definition of the geomorphic process
* An example of an ELT code: 103a. Lta 1, west side of mountains (1), basal till (03), wet (a).
