Sand building up bars at Elwha River mouth
Winter storms and a big slug of new sediment from behind the Glines Canyon dam are resulting in buildup of something not seen at the mouth of the Elwha in a century: sandbars deep enough to sink a foot into.
Here is one of his photos, dramatic to anyone who knows the usually rocky, ankle-turning cobble of the beach at the river mouth.

Here are some maps Miller made for Field Notes, to put the deposition in context:
Look how large the depositions of sand are at the river mouth, mapped by Ian Miller. Note too, how the shapes of the deposition reflect the prevailing west to east current of the Strait of Juan de Fuca.

Here's another look, with the depositions drawn on the landscape. A good way to visualize just how much sand has been pumped out of the Elwha.
The large amount of sand coursing out of the Elwha reverses a 100 year trend of erosion ... at least temporarily. The long-term effects are yet to be seen.
