These mounds of debris are what is left of some of the vegetation that once grew here. The smaller trees and woody vegetation are being pulverized and the resulting mulch piled up. Some of the oldest trees in Ottawa, including a rare Black Maple that was over 200 years old and a whole grove of 100+ year old White Pines, have been felled to make way for the road. This photo was taken looking west. The forested area to the left is going to be bulldozed and filled with housing at some point in the future.
