The parabola cantilever, with a glass floor of tempered and heat-strengthened glass, reveals an unobstructed view below. The cantilever is the result of an engineering technique that takes advantage of a balance formed by opposing tension and compression members and thereby eliminates the need for a more traditional superstructure of pylons and cables above the outlook. Corten steel was selected for its weathering properties and the relationship to the changing mountain face that it represents. The materiality of the outcropped steel will age and the size of the Athabasca Glacier will alter; both capturing a capacity to mark time with change.
