Mt. St. Helen looks like a great site; where exactly is the observing field? Is it possible to camp there?

The "observing field" is one of the last overlook pull outs near the Johnston Ridge Center. We get permission from the park service for a one nighter, but no camping tents...sleep in the car or a trailer, they don't want it to look like an overnight camping center. We do rent a sanican for unloading excess waste.
