|This subaqueous soil is on lake beds and
shorelines of freshwater lakes, ponds, and reservoirs. Burlingame soils
are formed in stony and boulder loamy glacial till material. Mapped
areas are irregular in shape and range from 0.5 to 40 hectares (1 to 100
acres). Slope ranges from 0 to 3 percent. Surface stones and boulders
typically cover 1-15 percent of the map unit with some areas consisting
of boulder pavement (rubbleland).
Typically, this soil has a very dark gray, grayish brown, or brown
sand or sandy loam surface layer, 20 to 40 cm thick. The substratum is
very dark gray, gray, or grayish brown silt loam, sandy loam, or sandy
glacial till deposits.
This soil is permanently submerged with up to 3 meters of fresh
water. All horizons have a pH of less than 6.5. Phosphorus concentration
in the upper 10 cm ranges from 16.8 to 743.5 ppm with a mean of 153.8
ppm. Carbon pools in the upper meter of Burlingame soils ranges from 23
to 340 Mg C ha-¹ with a mean of 152 Mg C ha-¹.
Included with this soil in mapping are small areas of Shannock and
Aquapaug soils in areas in sandy glacial fluvial material. Small areas
of Wickford and Tuckertown soils may also be included in areas where
organic layers overlie glacial parent materials. Included areas make up
about 15 percent of this map unit.
Fishing, swimming, and diving are common in the areas within this map
unit. Most areas are vegetated with native and invasive submerged
aquatic vegetation including white pond lily, yellow pond lily,
bladderwort, floating hearts, variable pondweed, fanwort, and variable
milfoil. Turtles are often found perched on the boulder outcrops of this
