The northern lights dance, and light the pioneer homes at the old Larson Ranch in Grasslands National Park.

What a night this was! I arrived at the Larson Ranch site in the Frenchman River valley to shoot some Milky Way panoramas, when, right on cue, the aurora broke loose.

Some aurora had been there since nightfall as a diffuse arc, but about 11 p.m. local time (Central Standard Time in Saskatchewan) the curtains began to dance and pulse with activity as a sub-storm hit, raining solar particles onto our atmosphere from down the magnetic tail of the Earth.

The aurora glow lit the old pioneer buildings of the Larson Ranch, one of the stops on the scenic backroad drive through the Park.

The Larsons ran their ranch by the Frenchman, or Whitemud River, from the 1920s until 1985 when they sold their ranch to the National Park system, forming the first land for the new Grasslands National Park.

The house at left is the original home of cowboy author Will James, who lived here for a time working on ranches in the valley before moving to the United States. He was from Quebec, where he was Ernest Dufault.

I shot this 360° panorama using a 15mm lens, shooting 8 segments at 45° spacings, each a 1-minute exposure at ISO 2500 and f/3.2 with the Canon 6D. I used PTGui software to stitch the segments into a equi-rectangular projection pan.
