Digging the Trenches for cable:

At Race Rocks: This composite image was made from a set of images taken from the balcony on the tower in mid-May of 2000. The route of the conduit installed in February is barely evident in the grass areas.

At Pearson College: Behind the observatory at Lester B. Pearson College, this trench carries the cable from the antennae donated by Telus  to the observatory.
