Recommended Method
Based on the synthesis of multiple well logs in and around Cass City, Michigan, the typical subsurface profile begins with surface to shallow subsurface clay (often with alternating thin sand or gravel lenses), progressing downward into thicker sequences of clay, followed by alternating sand and gravel zones. Below the surficial deposits, the most consistent bedrock sequence features interbedded shale and limestone, transitioning into thick water-bearing sandstone units. The sandstone is the primary aquifer for residential and high-capacity wells. Outliers and unusual lithologies have been suppressed to prioritize the most common sequence across the region.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 20 ft | Clay | Brown, gray; sometimes silty or gravelly; glacial till | Color: Brown/Gray Hardness: Soft |
20 – 40 ft | Sand and Gravel (mixed, minor clay) | Occasional sand or gravel beds with variable clay lenses | Color: Yellow/Gray Hardness: Loose/Soft |
40 – 70 ft | Clay (with minor gravel or sand layers) | Predominately clay, interbedded with occasional sand or gravel | Color: Gray Hardness: Soft |
70 – 100 ft | Sandstone and/or Shale | Soft shale and limestone layers transitioning to sandstone | Color: Gray/Green Hardness: Medium |
100 – 150 ft | Sandstone (water-bearing) | Coarse, white/gray/green sandstone; primary aquifer | Color: White/Gray/Green Hardness: Hard |
150 – 200 ft | Sandstone with Interbedded Limestone & Shale | Alternating beds, water-bearing, occasionally calcareous or shaly | Color: White/Gray/Black Hardness: Hard/Medium |
200 – 232 ft | Sandstone (with minor shale) | Thick, massive sandstone, terminates within regional aquifer | Color: White/Gray Hardness: Hard |
