Sieve after Bridge Two Rapid

Shortly after the second bridge rapid, there is a small horizon line with a tongue down the center.  At low flows, there appeared to be a significant amount of water going down the center and under a large flat rock that looked deadly to my eye.  The move to the right of it was not difficult, and I routed everybody through on directions on my descent, but is worthy of a quick scout to avoid accidentally dropping in the center.  It looked like a class III+++++ move to me.

Easy scout river right.
