Described by: Jim Turenne

Notes: Area is an abandoned sand & gravel pit, mapunit now has pitch pine (15-20' high) growing, pit described in a barren area, with only grasses and moss growing; water table > 200 cm; weather - sunny, dry, cool 50 degrees F.

Ap-- 0 to 9 inches; 85 percent dark yellowish brown (10YR 4/4) and 10 percent yellowish brown (10YR 5/8) and 5 percent very dark gray (10YR 3/1) loamy sand; massive; very friable, nonsticky and nonplastic; common very fine and fine roots and common medium; 5.2 Chlorophenol red; 10 percent rounded mixed gravel; abrupt smooth boundary. Ap colors should be moist color; Ap horizon is an altered horizon; colors are intermixed; horizon is probably topsoil material replaced after sand removal operation. Low chroma colors not related to saturation (reduction) - color of uncoated sand grains.

C1-- 9 to 22 inches; light yellowish brown (2.5Y 6/3) sand; single grain; loose, nonsticky and nonplastic; common very fine roots and common medium; 5.5 Chlorophenol red; 5 percent rounded gravel; abrupt smooth boundary. C1 horizon is stratified sands generally f-m sands; 22-28 cm 2.5Y 6/3 sand; 28-33 cm 2.5Y 5/3 fine sand; 33-38 cm 2.5Y 6/3 sand, w/5mm bands of 2.5Y 5/4; 38-55 cm 2.5Y 6/2 sand, w/3% fine gravel; low chroma colors not related to saturation (reduction) - color of uncoated sand grains.

C2--22 to 50 inches; light brownish gray (2.5Y 6/2) coarse sand; single grain; loose, nonsticky and nonplastic; 5.8 Chlorophenol red; distinct continuous strong brown (7.5YR 5/8) iron stains on sand and gravel; 5 percent subrounded gravel and 3 percent subrounded cobbles; abrupt smooth boundary. C2 horizon is stratified sand & gravel, mainly coarse sand; 55-71 cm 2.5Y 6/2 (dominant color, individual grains range from white to black), coarse sand 10% fine gravel; 71-74 cm 7.5YR 5/8 gravelly coarse sand - 20% fine & medium gravel, (accumulation of iron oxide); 74-125 cm 2.5Y 6/2 (color of quartz grain) gravelly coarse sand, 20% fine gravel, 5% med-coarse gravel, 2% cobble. Iron oxide coating on a coarse layer in C2 horizon at a depth of 71-74 cm not related to a seasonal high water table. (See description in footnote above.)

C3--50 to 54 inches; grayish brown (2.5Y 5/2) sand; single grain; loose, nonsticky and nonplastic; 6.0 Bromthymol blue; 1 percent rounded gravel; abrupt smooth boundary.

C4--54 to 80 inches; light olive brown (2.5Y 5/3) coarse sand; single grain; loose, nonsticky and nonplastic; 6.0 Bromthymol blue; 5 percent subrounded gravel.
