Lightning strikes cause wildfires in Michigan's Upper Peninsula

The Michigan Department of Natural Resources (DNR) has confirmed that lightning strikes caused both the Black River Fire and the Craig Lake Fire within the Rugged Terrain Complex in the Upper Peninsula. Investigators identified the cause by analyzing charring patterns on cedar trees and cross-referencing regional weather data with lightning strike maps.

As of the latest updates, the Craig Lake Fire is 90 percent contained and covers approximately 606 acres, while the Black River Fire is 70 percent contained and covers about 350 acres. The Ridge Fire, which spans 466 acres, is 50 percent contained, though its exact cause remains under investigation.

Firefighting efforts are complicated by severe to exceptional drought conditions in the region, which the DNR reports are at their worst in 20 to 30 years. Despite recent rainfall, the moisture deficit persists, and fires are reportedly burning up to two feet deep into the duff layer.
