We are in the desert here. Take plenty of water with you, even for the short walk to the pillar. The track to the pillar from Maryvale is quite remote, if you have any mechanical problem there you would have to wait some time before anyone comes by as the pillar is a tourist attraction, it would probably not too long anyway... at most a few days..., so take some extra food and water just in case. In case you DO run into mechanical trouble, do not leave your car.
