Vasquez Rocks is a public park north of Los Angeles known for its steep, tilted rock formations, and it has been used as a filming location in hundreds of movies and TV shows over the past century. According to a fan-run blog called The House of Fradkin-Stein, a stage-built version of the rocks, combined with a matte painting, was used by Universal for a scene in the 1931 Frankenstein. I found this information on that blog, not an official Universal source, which shows low barriers to entry: no studio, museum, or publisher approved this research, one enthusiast independently tracked down and posted a detail that official film histories tend to leave out. Mapping it on COVE adds a grassroots layer to a story usually told through official studio history. https://www.bewaretheblog.com/2018/08/vasquez-rocks-most-important-pile-of.html
