The mystery at the end of 2020 continues as another monolith has been spotted in Southern California that appears to be similar to one discovered in the Utah desert and another that was found in Romania. Al Jazeera reports that it is unclear who placed the monolith on a hiking trail in Atascadero, about halfway between San Francisco and Los Angeles, but the tall, silver structure has already drawn large numbers of hikers to the area after photos were posted on social media. The appearance of this latest monolith comes after several athletes posted on Instagram and YouTube that they were part of a group in Utah that pushed down the hollow stainless-steel structure there and took it away in a wheelbarrow to stop the environmental degradation being caused by people visiting the back-county site.
