Davison, MI48423-8598
The typical Davison-area geological profile consists of surface clays, interbedded sand, gravel, and clay zones, followed by thick shale, and capped by significant sandstone and minor limestone at greater depths. Most household wells reach bedrock or consolidated sandstone between 160-220 ft, yielding 10-15+ GPM.

Recommended Method
Based on multiple well logs from the Davison region and surrounding townships, the most representative geological sequence starts with thick surficial glacial clays and interbedded sand/gravel deposits to approximately 120-160 ft. Below this, wells consistently encounter layers of shale (often alternating with sand or clay), before terminating in thick sandstone bedrock, sometimes with minor limestone inclusions. Most residential wells achieve strong yields (10-15+ GPM or higher) by reaching the upper portions of the sandstone between 160 and 220 ft, sometimes slightly deeper. Outlier lithologies or exceptionally thick/lens-like units were omitted to produce this generalized, averaged model.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 20 ft | Clay (silty, occasionally mottled) | Brown/yellow or gray surface clay, sometimes with silt or sandy partings | Color: Brown/yellow/gray Hardness: Soft |
20 – 60 ft | Clay (sometimes sand/gravel inclusions) | Predominantly gray, blue, or yellow glacial clay, may contain minor sand or gravel zones | Color: Gray/blue/yellow Hardness: Soft-medium |
60 – 120 ft | Sand and Gravel interbedded with Clay | Coarse-to-fine gravel and sand, variable thickness; often water-bearing; interbedded with clay layers | Color: Tan/yellow/gray Hardness: Medium |
120 – 155 ft | Clay | Dense gray or brown clay, often with less permeability, occasional silt | Color: Gray/brown Hardness: Medium |
155 – 185 ft | Shale (with interbeds) | Dark gray or green shale, sometimes alternating with thin sandy, clay, or soft limestone lenses | Color: Green/gray/dark Hardness: Medium-hard |
185 – 220 ft | Sandstone (soft to medium hard) | Light tan to white sandstone, sometimes with minor shale or limestone seams, very good aquifer zone | Color: Tan/white Hardness: Hard |
220 – 260 ft | Sandstone, Shale, minor Limestone | Massive sandstone interbedded with shale and occasional limestone streaks, increasingly consolidated with depth; lower aquifer potential | Color: Tan/gray/white Hardness: Hard |
