The sun sets early within the deep canyons of the Colorado River outside of Glenwood Springs, Colorado. Despite it only being about 3 PM, the sun is just barely still touching the peaks of the cliffs as a trio of BNSF ES44AC's lead the Denver to Provo manifest through the canyon on UP's Glenwood Springs Subdivision. A UP maintenance of way trainset picking up scrap ties along the line has pulled into the siding here, across the river from the Grizzly Creek Rest Area, allowing the BNSF through freight to pass by as it heads west.
