This is a spot about a mile east from the Madison junction (map showing where I parked is here). There is thermal activity all around this area and I believe the steam you see is run-off from the bubbling water off to the left.
With mornings in the 30-degree range, the rising steam becomes even more dramtic.

Thanks, Cindy. The park’s beauty is very inspiring.
