Each category within a classification is listed in order of dominance and is separated from the other categories | Tv/Rc/O | | O//Tv | Tv//Tb-O Fv//Rc Fv/R Te/Tb/O | > 2 Or 50 Tv/Rc by a slash (e.g., Tv/R). Generally, the areas are divided so that up to three landforms or deposit types are identified within a given area. The | O/Or Tv//Rrc 0 | Tv/Rc/O 5 Tv/Rc-O Fv/Rc 2 > b Tb/O/Th Tv/O/Rc Tb/O O/Or/Tb O//Or-Rc Tb/Tv/O Te/O Or//Th Ge/G classification system is also used to denote the approximate percentage of landforms occurring within an outlined area, but those which | T Tv/Rc/O Tv/O/Rc O/Or 0 > / O O//Tb Rrc/Tv/O e 5 Tv/O/Rc O//Tb-Or / | 0 Tb/Te Tb/Tv/O b | 5 v 7 form less than 5 percent of the area are not included in the classification. Four variations of the landform system are as follows: | > Tb/O/Tv O/Or Tv/Rc-O Or/Tb/O T | 2 Tv//Rc-O T Ge/Ev Tb/O / | v Tv//Rc-Te O/Or/Tv Tl T > | Tv/Rc-O | Te/Tv | 7 Rc/Tv Tv/Rc/O | 5 | | Tv/O-Rc O | | 0 > O/Or 2 > Fp | | | | | | | Te/Tb Rc/Tv 5 1. Where three different landforms are included in a single map unit they are each separated by a single slash (/) and their relative 0 | | | Tr//O O//Tb-Or > | Tv/Rc/O | 0 Te/Tb/O | 0 O O/Tv | | O | Te/Tb Tb/O Tv//O Tv/Rc 5 0 percentages are (60 - 80), (15 - 35), and (5 - 15). | Ov | 0 5 Tl/Te | 0 Tv/O/Tb Tv/Rc/O | Te//Rc-O 5 2 Tv/O/Rc Tv/Rc Tv/O-Rc > | T 2 O/Tb/Or | O/Or Tb/O/Or 0 | Gv/Gt Ov | O//Or-Rc Tl/Te | Te/O | Ov 0 Tl/Te Ov /Tb 0 Tv//Rc O/Or 5 Rc 5 //Rc O Tb/O 2. Where two landforms are included in a single map unit, a double slash (//) or single slash (/) is used to separate them, and their | T T O//Or O/Or/Rc Rc//Tv-O > 2 | Tv//Rc | Te/Tb/O | | Ov Tv//Rc-O | | | | Tv//Rc-O Or//O Te/Tb Tb/Te relative percentages are (85 - 95) // (5 - 15) for double slash, or (60 - 85) / (15 - 40) for a single slash. | Fv/Rc T 1 O > Tv/O/Rc Th/Or Tb/Te / | Tv/O/Rc > R Tv/Rc-O Tb/O/Th Y O c | Tv/Rc Tv/Rc/O / | Tv Tv/O/Rc O/Or Th/O/Or Mr | Tb/Tv Tv/Rc/O Gv//Rc | Gv/Gt | Te/Gv O 3. A hyphen between two landform types indicates that they are approximately equal in area. For example, Tv-Rc indicates that till A Tb/Tv/O O/Or | | Rc/Tv | O/Or Tb/Tv/O Rc/Tv Ov 0 O/Or/Tb O/Or Or/Th | | | veneer and rock concealed by vegetation or a thin regolith are equal in area. 0 O/Or/Rc O/Or/Rc O//Tb O O Or Tb/ > | 5 Tv/O/Rc O//Tb | | | 7 O/Or/Tb DEPARTMENT OF NATURAL RESOURCES B | Tl T | | 5 O/Or O/Or | | O/Rc/TV 0 0 O F/G Tb/O/Tv | Tv/Rc Ov 5 /Tb 2 | O Ov Or/Tb/O Tv//Rc-O Rc/Tv Rc/Tv T O/Tv O/Tb/Or /O 4. A composite symbol is used to show combinations of the above cases. For example, T indicates that about 60 - 85 percent of the GEOLOGICAL SURVEY | Ov Tv/Rc/O Tv/O/Tb | | T Ov Tb/ Tv//Rc-O Th/Te/O Tv/Rc/O Tb//Rc | Fv/Rc | c area is covered by fluvial sediment, 15 - 40 percent by glaciofluvial sediments, and is underlain by till.
