The Rocky Mountains

	Etching, art by Albert Bierstadt, 1866, 36x26.5 inches, Lander's Peak
	Etching was washed with water, Orvus, and Sodium Hypochlorite. Etching was then mounted to linen and masa with a water soluble adhesive. Sodium Hypochlorite was then airbrushed onto the etching to remove the discoloration. Restoration was performed using airbrush, watercolor, and colored pencil.
