Well, here's one example. Placing equipment in the lower spillway rock cleaning area. Look at the drone pic from the top of the crane. Quite the height.
Another curious item: Third picture down shows an excavator to which they affixed a large tire to the bucket. The tire is compressed. They cut the tire sidewalls to hang downward so they could use it as a giant squeegee. This allows a "rubbing" of the "fines" debris downhill as this debris is being power washed away leaving clean rock.
