The figure below shows the Sunshine Canyon landfill in Sylmar, California, an example of topographic change due to landfill operations. The operation and expansion of this landfill continues to be a controversial topic in the local area. The close proximity of the landfill site to a major transportation artery is a reminder that visual impacts of human geomorphic activities can be significant.
