It is a complete mystery. I like that. Gap Parowan is in southern Utah along Interstate 15, about a 25-minute drive north of Cedar City. The route to the Gap is somewhat convoluted. The best way to find the site is to go to one of the gas stations in the center of Parowan and ask for directions.
Most locals seem to know how to get to the site.
The road to the Gap is in good shape and passable to all vehicles. Parowan has all services, though primitive camping would be possible near the Gap. People still send me letters.
