This story was originally published by High Country News and is a collaboration with Grist. On a wet spring day in June, fog shrouded the Mission Mountains on the Flathead Indian Reservation in northwest Montana. Silver beads of rain clung to blades of grass and purple lupine. On a ridge overlooking St. Mary’s Lake in the southeastern corner of the reservation, the land was mostly cleared of trees after state-managed logging operations. Some trees remained, mainly firs and pines, spindly things that once grew in close quarters but now looked exposed without their neighbors.
