If you were going to use it, your car's navigation would probably route you there, and you wouldn't need to look for it. FWIW.
Of note, right by the Shasta station was a large Supercharger bank, so the planning for this was probably done before the Rivian deal to use Tesla chargers and the free adapter program Rivian implemented. They may have kept that one anyway, considering the Shasta Area is probably underserved and fits Rivian's target market for their stations ("adventure" areas)
