Colaizzo's work focuses on landscapes that blur the line between natural and unnatural. It contextualizes man’s mark on the earth with a broad view of nature. It involves ideas about natural history, cosmos, human progress, mystery, and spirit.

 The imagery is made by using multi-block woodcuts printed by hand and etchings on copper to create landscapes that are inspired by the coal industry’s mark in Northeastern Pennsylvania. The scarred earth and mountains of coal are evidence of “human progress,” symbolizing man’s relationship with the earth, trying to seize and conquer it for our own benefit rather than relish in its mysteries.
