A representative geologic profile for Boyne Falls and adjacent areas consists of an upper sequence of sand and gravel (often mixed with clay, silt, and stones) extending from the surface to approximately 30–100 feet. This is followed by variable thicknesses of clay, silt, and fine sand, commonly alternating with layers of shale. Below 100–140 feet, limestone (often fractured or hard) becomes more prevalent, commonly interbedded with additional shale or blue clay. In deep wells, thick units of limestone dominate below about 200–230 feet before grading down into bedrock, predominantly limestone and dolostone, sometimes fractured or water-bearing. Wells targeting 5–15+ GPM for residential use typically draw from coarse sand/gravel units or productive fractured limestone/shale zones between 80–200 feet.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 35 ft | Sand & Gravel with Clay | Brown or black, sometimes fine sandy, occasional stones; uppermost surficial material and principal unconfined aquifer where thick enough | Color: Brown/Black/Grey Hardness: Loose to compact |
35 – 60 ft | Sand (Water-Bearing) and Silt/Clay Interbeds | Fine sand, sandy silt, and clay interbeds, occasionally water-bearing; transition zone downward from gravel to finer units | Color: Brown/Grey Hardness: Medium |
60 – 110 ft | Clay, Silt, and Occasional Fine Sand | Predominantly brown, blue, or black clay with interbedded silt/fine sand; relatively low permeability, acts as a confining unit above deeper aquifers | Color: Brown/Blue/Black Hardness: Hard/Plastic |
110 – 145 ft | Shale and Limestone Interbedded | Alternating hard/soft shale and limestone; sometimes 'blue shale', with occasional fractured limestone, potential aquifer zone | Color: Gray/Blue Hardness: Varies (Soft/Hard) |
145 – 200 ft | Limestone (Hard, Fractured) with Minor Shale/Clay | Thick, commonly brown/gray limestone zones, sometimes fractured or hard, often productive water-yielding intervals | Color: Gray/Brown Hardness: Hard, Fractured |
200 – 312 ft | Limestone with Interlayers of Blue Clay and Shale | Dominantly limestone with occasional blue clay, shale, and hard or broken rock intervals; main bedrock aquifer sequence | Color: Gray/Brown/Blue Hardness: Hard, Some Broken/Fractured |
