<span style=”font-weight: 400;”>Hi folks. As you know, In our hike of the route we scouted this section but did not climb over Grasshopper Pass. </span>
In Secor’s The High Sierra [page 176, 3rd edition], he describes the ascent up the north side of Grasshopper Pass “The pass is class 3 on its northern side (loose rock!)…” If Secor  puts an exclamation point on loose rock it is certainly worth paying attention to.
For what it’s worth here is a pic https://drive.google.com/open?id=0B0kTYChKY8wmby1HSUtubEJQRFk of “Grasshopper Pass” that I took on our Aug 2014 trip. We walked to near the base of it before Don decided that it looked to have too much loose junk for his taste. So the pass doesn’t look particularly technically challenging, but it does look like a ton o’ loose crap.
As a guess (but no means certainty), conditions may have changed for the worse since the info roper’s class 3 was based on. I couldn’t find any reports of anyone attempting the north side of the pass on foot (wood’s lake side) in like the last 30 years. At first blush, it appears it might be “post climate change” talus. My experience with this talus is that is far more unstable than regular talus. As such, it may not be very safe if you get on it and it turns out to be unstable. BUT the only way to find out is to actually put your shoes on the stuff. Could just be class 3 with loose rock.
Safe travels, -alan
