Thanks for looking and for the insights.

It was about 4200 feet which is mid-elevation for here, so not subalpine or beyond.

These are so difficult…

Was this relatively low elevation? Doesn’t look like the subalpine or alpine, but could be wrong. My source (working key T. Goward gave me) indicates that S. rivulorum is mostly arctic-alpine, with poorly-defined main branches which branch close to the base. I’m seeing a more typical sprawling, well-defined main branch. I personally just call everything like this S. tomentosum, but there’s a complex of poorly-understood species surrounding this basic morphology.
