Unfinished Painting of An Unidentified Location

Unf Mystery

The subject matter of this unfinished painting has not been identified. The distance is complete well enough to tell us that it is not of a mountain. It has the resemblance of Crater Lake, but the colorful clouds would be unusual for her as she normally did that scene in pure blue skies with just a dash of white clouds. Possibly an early morning scene somewhere on the Columbia River?
