Rescue crews described the boulder as massive and possibly weighing more than 700 pounds
Apparently they started on the Waterfall Trail before going off-trail.
I watched the rescue video and can't quite figure out where they were at. The way the situation is described, it's a good thing the injuries weren't more severe.
