A passage from Wild Edible Plants of Colorado:

Two Wintercress species are found in Colorado – non–native Barbarea vulgaris, and native B. orthoceras. The non–native species is a bit more common than the other. They are similar in appearance and found at elevations of 5500’–9500’, almost always in moist/lower–lying soils.

A passage from Wild Edible Plants of Arizona:

In Arizona, it grows between 5000’–10000’ and almost always in the moist soils of meadows and streamsides. Look for it from the San Francisco Peaks and Mogollon Rim to the White Mountains and Pinaleños.
