This picture shows Gilman's Cletrac Trailbuilder Model, blading snow out of one of the town streets. Due to the lack of power of this Cletrac it cannot handle a full blade of snow, making it inefficient for the handling of large areas of snow as seen in this picture."Donor: Friends of Mineralogy, Colorado Chapter.Celtrac trailbuilder plow clearing snow from the street; snowy mountains are in the background.3 1/2 x 3 1/2 inchesblack-and-white photographsUnderground mining -- ColoradoZinc mines and mining -- ColoradoSnow removal -- Colorado -- GilmanStillImage
