2.04.9 Soils Resource Information
The Glendive series is a member of the coarse -loamy, mixed (calcareous), frigid
family of Ustic Torrifluvents. A representative profile of Glendive sandy loam, sample
point MC10 about 150 feet east and 2,105 feet north of the southwest corner of section
21, T 7 S, R 102 W, at an elevation of 5,402 feet is:
A11 0 to 4 inches; pale brown (10 YR 6/3) sandy loam, brown (10 YR 5/3) moist;
weak thin platy parting to fine granular structure; soft, very friable, non -sticky
and non -plastic; calcareous; 1 to 3 percent gravels; many fine and very fine
roots; discontinuous peaty layer at 3 to 4 inches; bottom one inch is pink (7.5
YR 7/4); pH 7.6; abrupt wavy boundaries.
Al2 4 to 8 inches; light yellowish brown (10 YR 6/4) very fine sandy loam, brown (10
YR 5/3) moist; strong very thin platy structure; soft very friable, non -sticky and
non -plastic, calcareous; many fine and very fine roots, common medium roots;
bottom 1/4 inch is a thin platy clayey horizon; coal fragments throughout; pH
7.5; clear wavy boundary.
C1 8 to 19 inches; pale brown (10 YR 6/3) very fine sandy loam, brown (10 YR 5/3)
moist; moderate thin platy parting to fine single grained structure; slightly hard,
very friable, non -sticky and non -plastic, calcareous; common fine and very fine
roots, few medium and coarse roots; at about 16 inches occurs a thin (1 in.)
clayey pinkish gray (10 YR 6/2) layer; pH 7.6; clear wavy boundary.
C2 19 to 74 inches; variously colored (7.5 YR 7/4, 10 YR 6/3) stratified very fine
sandy loam and gravelly loamy sand, brown (10 YR 5/3) moist; massive
structure slightly hard to slightly soft, very friable, non -sticky and non -plastic,
calcareous; common fine and very fine roots, non -sticky and non -plastic,
calcareous; few fine and very fine roots; top 3 to 4 inches is a pink (7.5 YR 7/4)
loamy medium sand; at 34 inches is a 2 inch silty layer; other wavy horizons
within; pH 8.0.
The surface horizon is very fine sandy loam or loam. Peaty horizons occur
between 3 and 18 inches. Gravely or very gravelly lenses occur below 40 inches. The
control section is mostly fine sandy loam or loamy sand with 1/2 to 6 inch lenses of
coarser or finer textures, but clay typically averages 5 to 18 percent. Typically these
soils are calcareous throughout, but may be leached to 6 or 8 inches. Rock fragments
range from 0 to 15 percent.
