Michigan's Highest Point: Upper Peninsula's Porcupine Mountains

The Upper Peninsula (UP) has Michigan's highest elevation.

• Highest point: Mount Arvon (1,979 ft / 603 m) — Baraga County, Huron Mountains. Correction: Porcupine Mountains' Summit Peak is 1,958 ft; Mount Arvon is slightly higher.
• Porcupine Mountains Wilderness State Park: Summit Peak (1,958 ft), Lake of the Clouds, old-growth forest.
• Average UP elevation: ~800 ft.
• Lower Peninsula average: ~650 ft (highest: Briar Hill 1,706 ft).

Why the UP Is Higher

• Ancient Canadian Shield bedrock (Laurentian Upland).
• Glacial scouring exposed resistant Precambrian rock.
• LP covered by thick glacial drift, softer sedimentary bedrock.

Visiting Mount Arvon

• Seasonal logging roads (May–Oct); high-clearance vehicle recommended.
• Short hike from parking area; benchmark disk at summit.
• Views: Lake Superior, Huron Mountains, Keweenaw Peninsula.

The UP's rugged terrain defines its climate, ecology, and "Yooper" identity — distinct from the mitten.
