BURLINGAME SERIES

The Burlingame series consists of subaqueous soils that are permanently submerged in 0 to about 3 meters of water on lakeshores of freshwater ponds, lakes, and reservoirs. The soils formed in mixed lacustrine material overlying till. They are typically underlain by supraglacial meltout or lodgement till. Slope ranges from 0 to 5 percent. The mean annual temperature is about 9 degrees C and the mean annual precipitation is about 1143 millimeters.

TAXONOMIC CLASS: Coarse-loamy, mixed, active, nonacid, mesic Aeric Frasiwassents

TYPICAL PEDON: Burlingame sandy loam on a 1 percent slope permanently submerged beneath 1 meter of fresh water. (Colors are for moist soil unless noted differently.)

A2--3 to 9 cm; 50 percent light brownish gray (10YR 6/2) and 50 percent strong brown (7.5YR 4/6) fine sandy loam; massive; 2 percent organic matter; nonfluid; nonsaline; moderately acid (pH 5.8); abrupt boundary. (Combined thickness of A horizons is 0 to 21 cm.)

AC--9 to 18 cm; 50 percent gray (10YR 6/1) , 50 percent black (10YR 2/1) sandy loam; massive; 4 percent organic matter; nonfluid; nonsaline; strongly acid (pH 5.2); abrupt boundary.

CA--18 to 35 cm; 48 percent olive brown (2.5Y 4/3), 48 percent very dark grayish brown (10YR 3/2) and 4 percent strong brown (7.5YR 5/8) oxidized very gravelly sandy loam; massive; 40 percent gravel; 5 percent organic matter; nonfluid; nonsaline; strongly acid (pH 5.5); abrupt boundary. (Combined thickness of AC and CA horizons is 0 to 36 cm)

Cg1--35 to 48 centimeters; dark grayish brown (2.5Y 4/2) loamy sand; massive; 8 percent gravel; 1 percent organic matter; nonfluid; nonsaline; strongly acid (pH 5.2); clear boundary.

Cg2--48 to 57 centimeters; gray (2.5Y 5/1) fine sandy loam; massive; 1 percent organic matter; nonfluid; nonsaline; moderately acid (pH 5.8); abrupt boundary.

Cg3--57 to 67 centimeters; light brownish gray (2.5Y 6/2) sand; massive; nonfluid; nonsaline; moderately acid (pH 5.7); abrupt boundary.

Cg4--67 to 91 centimeters; gray (2.5Y 5/1) loamy fine sand; massive; nonfluid; nonsaline; moderately acid (pH 5.9); clear boundary.

Cg5--91 to 117 centimeters; gray (2.5Y 6/1) loamy fine sand; massive; nonfluid; nonsaline; moderately acid (pH 5.8); abrupt boundary.

Cg6--117 to 128 centimeters; olive gray (5Y 5/2) silt loam; massive; nonfluid; nonsaline; moderately acid (pH 5.8); clear boundary.

Cg7--128 to 160 centimeters; gray (5Y 5/1) loamy sand; massive; nonfluid; nonsaline; moderately acid (pH 5.8). (Combined thickness of Cg horizons is 100 to 170 cm.)

TYPE LOCATION: Washington County, Rhode Island; typical pedon is located in a northwest cove of Smith and Sayles Reservoir; USGS Chepachet, RI topographic quadrangle; Latitude 41 degrees, 53 minutes, 45 seconds N. and Longitude 71 degrees, 40 minutes, 51 seconds W. NAD 1983.

RANGE IN CHARACTERISTICS: The soils are permanently submerged. Stones and boulders typically occupy .01 to more than 15 percent of the soil surface.

The A horizon, where present, has hue of 2.5Y, 10YR, or 7.5YR, value of 2 to 6, and chroma of 1 to 3. Texture ranges from silt loam to coarse sand. Reaction ranges from strongly acid to moderately acid. Rock fragments range from 0 to 5 percent.

The CA or AC horizon, where present, has hue of 2.5Y, 5Y, 10YR, value of 2 to 5, and chroma of 1 to 2. Texture ranges from sandy loam to sand. Reaction ranges from very strongly acid to moderately acid. Rock fragments range from 0 to 40 percent.

The Cg horizon has hue of 2.5Y, 10YR, 7.5YR or is neutral, value of 3 to 5, and chroma of 1 or 2. Texture ranges from silt loam to sand. Reaction ranges from very strongly acid to neutral. Rock fragments range from 0 to 40 percent.

COMPETING SERIES: There are currently no soils in the same family.

GEOGRAPHIC SETTING: Burlingame soils are found on permanently submerged till on shorelines and shoal deposits in freshwater ponds, lakes, and reservoirs Slope ranges from 0 to 3 percent.

GEOGRAPHICALLY ASSOCIATED SOILS: These are Shannock (T), Tuckertown, Wickford, and Aquapaug on nearby landscapes. Shannock (T) soils are on lake bottoms and have an umbric epipedon. Tuckertown and Wickford soils have greater than 40 cm of organic material. Aquapaug soils are sandy throughout the particle size control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Subaqueous soil, peraquic soil moisture regime, moderately high or high saturated hydraulic conductivity due to soil texture. The soil is permanently submerged with water.

USE AND VEGETATION: Areas of this soil are used for recreational fishing, swimming, and aquatic wetland habitat. Vegetation includes bladderwort (Utricularia sp.), fanwort (Cabomba caroliniana), variable milfoil (Myriophyllum heterophyllum), white water lily (Nymphaea ordorata), and yellow water lily (Nuphar variegatum). Water bodies these soils are mapped in have an average pH of 6.5 and average temperature of 20C during the summer months.

DISTRIBUTION AND EXTENT: These soils occur in freshwater ponds of the Northeast in MLRAs 144A and 149B. This series is of small extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts.

SERIES ESTABLISHED: MLRA 144A Freshwater Soil Survey Project, 2012.

REMARKS: The series is named for Burlingame State Park located in Charlestown, Rhode Island.

Diagnostic horizons and features recognized in this pedon include:
1. Peraquic feature - positive soil water potential (permanently submerged) at the soil surface
2. Ochric epipedon - the zone from 0 to 9 cm (A1 and A2 horizons)
3. Particle size control section - 25 to 100 cm (CA, Cg1, Cg2, Cg3, Cg4, and Cg5 horizons)
4. Aeric feature- 48 percent of the zone from 18 to 35 cm has hue of 2.5Y and both color value moist of 4 and chroma moist of 3 (CA horizon).
5. Nonacid reaction class - the zone from 48 to 100 cm. has a pH in water, 1:1of about 5.5 or more.
