Intersection of Hwy 40 and Rose Ridge Road.
Duchesne County, UT
Roadside stop in the shade at noon. There was a small pond alongside the highway with a small meadow at the forest edge here in the Mountains of Utah. The Marble appeared very white vs the buffy or off-white of the Large Marble thus the ID of Pearly Marble which would be a lifer!
