Dave Bell was surprised to see light pillars over Pinedale Friday morning (March 16, 2018).
"The weather conditions were not what historically has created these beautiful lights. It was about 19F, light wind and dry. We have had no measurable snow in the past several hours. But, nonetheless, we had a decent display of light pillars to the south of Pinedale. I think the further lights are rigs and production facilities on the south end of the mesa. The big one, right of center, is the rig and fracing operations on the north end of the mesa above Pinedale. Taken about 6:00AM. Canon 1DC, 24-70 at 24mm, 15 seconds at f2.8, ISO 320." - Dave Bell
