HAL's Alpha Ridge Park Solar System Walk
The solar system walk was the brain child of HAL member Colin Brinster who performed many tasks as part of his Eagle Scout work. The hardware was provided by the Max Cowan Foundation. Joel Goodman was the HAL board member who drove this effort. Thanks to Howard County Recreation and Parks for their support.
Since the solar system walk is spread across 0.4mi of the park, it is open and ready for you during all hours that the park is open - usually dawn to dusk, seven days a week. This walk is laid out in a loop so that you start and end at the observatory.
