Well Drillers Near Bruce Crossing, Michigan

A geological estimate for the Bruce Crossing area.

Detailed Summary

Based on synthesis of sampled well logs from Bruce Crossing and surrounding Ontonagon County townships, the representative geological section begins with 15–40 ft of sand or mixed sandy material, underlain by sequences of clay and hardpan (variously 60–110 ft thick in total, sometimes with alternating clay and hardpan). This is followed by increasing sand or mixed sand/clay intervals (commonly 20–100 ft), below which a notable hardpan and/or clay with stones layer may be present. The glacial-overburden sequence typically totals around 120–140 ft. At depths from 120–170 ft (deeper in some wells to 240–290+ ft), wells encounter sandstone bedrock, sometimes with minor shale or limestone, which acts as the primary aquifer. Outliers (very deep or shallow features, unusual lithologies) are excluded.
