After several pictures and videos were posted on social media, the structure drew hikers.
The 10-foot-tall structure was similar to two others discovered recently in the Utah desert and in Romania. And like them, the origin of the California edifice was also unknown.

However, a Facebook post by the City of Atascadero said the monolith was torn down by a group of young men who had travelled over five hours to see it.
As per an AP report, the monolith was replaced with a wooden cross, which also disappeared.
“I can’t say its aliens, but it was here and now it’s gone,” Terrie Banish, deputy city manager of Atascadero, California, told Reuters.
“It appeared only (Wednesday) and in the middle of the night someone hauled it off,” she added.
Unlike the other to structures, the California monolith was not placed in the ground well and could be “knocked over with a firm push”—possibly injuring hikers if it were to fall.
The inexplicit appearance disappearance of the strange structures left many intrigued, and drew speculation on who was behind them.
