Grignak

Grignak

Grignak is a character in Galaxy Quest. He is a large rock monster who attacks Peter Quincy Taggart. In Iceland, smaller, inanimate grignaks are used to mark trails in national parks. The Colonel's Regiment first discovered grignaks during their trip to Þingvellir National Park. A trail of grignaks led them out to a prehistoric farm, before they were replaced by small, less interesting poles which led them to the visitors' centre. Grignaks were also prevalent on the Mount Sulur trail. The summit is marked by a larger, shoulder-height grignak.
