Earth Day 2016, from moon rise to moon set over the Spring Creek railroad trestle, near Lewistown, Montana. This is an interval photograph, with the full moon photographed every three minutes from 8:38 p.m. until 6:30 a.m. the next morning. Combining the frames shows you the moon's dusk to dawn path across the night sky. It was a micro-moon, the smallest full moon of 2016, and Jupiter is visible between clouds near the top right.
I don't photograph man-made structures very often, but the full moon passing over this old trestle was too challenging to pass up. The bridge was completed in 1913 by the Chicago, Milwaukee, St. Paul and Pacific Railroad. It's a "single track gauntleted trestle," 1,300 feet long and 80 feet high over the creek. The company filed for bankruptcy in 1977 and was eventually sold in 1985. The Spring Creek trestle was deemed unsafe for use in the 1980's, and ponderosa pine trees now grow between the rails just east of the trestle.
