Weird Wired Power Pedestal
Upon hooking up to electric I turned all breakers off, plugged in my 30 amp cord and turned on the breaker marked "30." Went for a walk, etc. Couple of hours later wife went to turn on microwave an...

You're sure there's no 50A receptacle around? Maybe there was at some time.
Of course, it's not unusual when there is a 50A circuit (and a 30A circuit) to have the 50A breaker be a main and the 30A (and 20A, assuming there's one of those) fed from legs of the 50A internally. Probably either there is/was a 50A previously, or they wired the place with the place with an eye to upgrading the sites at some point in the future...but who in their right mind would go to all that much trouble and then not spend the extra $25 or whatever for a 50A socket?
At any rate, I expect you'll find you need both the 50A and the 30A breakers on to get power. No safety issues if that's the case (assuming the voltage and polarity are correct etc.); there's nothing in the electrical code that prevents having multiple breakers in series for a circuit, even when it's not particularly useful to do so.
