If you're talking about the moraine, bring a helmet as you cross. A partner of mine literally flew from an unstable boulder that was tipped. There is a really good chance he might have died without a helmet, as he smacked his head full force on another rock upon landing. Moraines at glaciers' bases are frequently a bunch of loose, unstable, unbalanced rocks just waiting to find equilibrium (read: shift, as soon as you release it).

The ability to fly is a plus in such terrain.

Reminds me of the Carbon Glacier on Mt Rainier. Completely covered with rock. I hiked to the base of it years ago, a great hike through lush forest, but didn't go on it. At the snout we sat and watched, every minute or two another large rock would tumble off the end as it melted away.
