This photo pair features a view of the Riley Creek railroad trestle looking east. Completed in 1922, this trestle was the one of the last major gaps bridged on the railroad route from Seward to Fairbanks, and now sits on the National Register of Historic Places. Notice the standing dead spruce in the 1929 photo? Those may be evidence of the 1924 wildfire that swept through this area. Notice also that the forest has filled in considerably with more spruce and deciduous trees and shrubs? This is likely from the recovery of the forest after logging and the effects of the fire. Much of the gravel bar exposed in the 1929 photo has been claimed by vegetation in the later photo.
