In 1988, Kirschvink was recognized as a "Rising Star" in Southern California by the Los Angeles Times.^[5] In 2021, Caltech settled with the Department of the Interior to pay $25,465 for damages to petroglyph sites in Volcanic Tablelands after they were damaged by Dr. Kirschvink on Earth Day 2017.^[6][7]
