Standard Ticketing Alert: Enter the monument through the Gateway Arch Visitor Center, which faces Fourth Street and the Old Courthouse. The Gateway Arch legs are exits only. Please allow at least 30 minutes to go through security. Tickets sell out early and often, advance reservations are strongly recommended.
Dark Sky Missouri coordinator Don Ficken will discuss the impact of light pollution and a way you can measure it using nothing more than a cell phone. This program will be presented outdoors on the entrance plaza, but could be moved just inside the arch main entrance in the event of inclement weather.
The talk will last about an hour, and the telescope viewing will follow.
This is a free event and no registration is required.
For more information, please contact Gateway Arch National Park Ranger Rich Fefferman at 314-655-1704
