I camped at that water crossing, just in the background of the second picture. I'd say you should head upstream the hundred yards or so to the shallower crossing. I didn't know about the better spot at the time we were there.

Since you're looking for reports, I did the section last summer between Devils Postpile and Edison Lake. And got lost twice. If you read the report, it might be helpful when you come to those spots. Lost on the JMT: Reds Meadow southbound

In June, '08, I found the water crossing on the South Fork Kings River dicey (near the Taboose Pass junction). It looked downright dangerous -- deep and swift. We explored upstream from the trail crossing and found a decent log to cross. I just don't understand why SeKi people don't create a bridge or at least drop a log at that point. My son hiked that section the year before and encountered several hikers who had serious trouble there. One lost a boot, another got a gash so bad he used a needle and thread to close it.
