February sunrise light is best for the classic Mesa Arch photo pioneered by Tom Till.
As far as standing on the arch it looks like a pretty sturdy arch and the greatest threat would be slipping of the edge.
Many years ago people drove Jeeps across Gemini Bridge Arch. Then some teenage driver, not paying attention, drove off the edge and parached. That put a stop to driving across the arch. The latest issue of Utah Life Magazine has an article and photos of flying a small airplane through several of the larger archs.
In the distance, you will see the washer woman.
Wonderful image Fred. Great lighting!
