Saranac, MI48881-0001
Typical Saranac-area wells encounter alternating glacial sediments (clays, sands, gravels) with a prominent water-bearing sand/gravel layer between 40–130 ft, underlain by deeper clays or, rarely, bedrock.

A representative geological profile for the Saranac, MI region consists of an upper sequence of variable surficial loams, sands, and gravels (0–35 ft), followed by thick clay sections (often red, gray, or blue, sometimes interbedded with gravels and sands) extending to about 80–120 ft. Between 30–130 ft, significant intervals of water-bearing sand, sand/gravel, or fine sand are common and serve as the primary aquifer for residential and higher-capacity wells, producing 10–50+ GPM. In most cases, deeper layers return again to dense clay or hardpan, and in a minority of deeper wells, shallow bedrock (shale/sandstone) is found around 300–340 ft. Most residential wells are cased through the upper silts and clays and terminate within the main sand/gravel aquifer zone. Static water levels typically range from 13–89 ft below grade, depth depending on site and aquifer. Grouting is usually bentonite or cement from surface to at least 30 ft, using rotary or cable tool methods.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 7 ft | Loam/Sand/Gravel | Surficial loams, sand, or gravel with variable fine or sandy textures | Color: Brown/tan/gray Hardness: Soft |
7 – 35 ft | Clay (sometimes with cobbles or gravel) | Dense clay, often with cobbles or occasional sand/gravel interbeds | Color: Red, gray, blue Hardness: Firm to hard |
35 – 50 ft | Sand/Gravel | Water-bearing sand or sand & gravel intervals; main residential aquifer | Color: Tan/yellow/gray Hardness: Loose |
50 – 80 ft | Clay with interbedded gravel/sand | Mostly clay, possibly layered with sand/gravel streaks | Color: Red, gray, blue Hardness: Firm |
80 – 130 ft | Sand/Gravel (water-bearing) | Major sand and/or sand & gravel aquifer; typical for high-capacity wells | Color: Tan/yellow/gray Hardness: Loose |
130 – 250 ft | Clay (with some stones) | Thicker clay sequence, locally with stones/cobbles | Color: Gray/blue Hardness: Hard |
250 – 310 ft | Shale | Soft to semi-indurated shale bedrock (rare, only in deepest wells) | Color: Dark gray Hardness: Soft rock |
310 – 342 ft | Sandstone | Friable sandstone, local bedrock aquifer (rare/outlier) | Color: Light gray Hardness: Medium to hard rock |
