The Catalyst is “The Newsletter for Interpretation in California State Parks.”

In chemistry, a catalyst is a substance that starts or speeds up a reaction. Likewise, in The Catalyst, you will find thought-provoking, useful, and entertaining information that will help your work or fuel a discussion. The Catalyst includes everything from news stories to reflections from interpreters; from ideas for programs and recommendations of tools, to guidance and advice on issues related to interpretation.
