Edit: If anyone wants to skip this crossing, the unmaintained "Old Trail" starts at Whitney Portal, just a little past the store, and climbs 30 switchbacks, then joins the Main Trail, just steps from this stream crossing. It joins the trail above/after the crossing heading up, so no crossing is required. Old trail description and pictures is here. It is unmaintained, and getting pretty rough with large boot-size rocks in the path.
July 4: Here is a picture of the trail in Bighorn Park, just before Outpost Camp, from this report.
