This blueprint shows the side profile of the proposed tramway to be built in Cassiar. It includes scale drawings of the crusher building, power house and support structures. The degree of tilt of the support structures are marked down where applicable. The side profile is divided into five sections due to the scaled height in elevation and the lack of drawing space. Annotation written along the leading edge of the blueprint reads "Proposed Tramway Riblet".
