Until the early 1950s, Pacific Northwest communities outside the larger metropolitan areas were passed over for natural gas service. In 1953, Pacific Northwest businessmen Lester Pettit, Spencer Clark, and Stewart Matthews formed Cascade Natural Gas Corporation to serve these communities with clean, affordable natural gas. Cascade serves a diverse territory covering more than 32,000 square miles and 700 highway miles from one end of the system to the other. Interstate pipelines transmit Cascade’s natural gas from production areas in the Rocky Mountains and western Canada. The Cascade headquarters is located in Kennewick, Wash.
