While playing tour guide for some out-of-town friends, I wandered along the Hoh upstream of the trailhead on Tuesday. Visibility seemed reasonable, for the Hoh. However, that was before the furnace-like heat that we are experiencing now. That has to bump up the melt water off the glaciers on both the Hoh and the Elwha. If you can, I would wait for the cooling trend near the middle of next week.
