It's the Dead Horse Point State Park, attentively rendered by "the famous Louis Heinzman." Wiki on the first: "The park is so named because of its use as a natural corral by cowboys in the 19th century, where horses often died of exposure."
As for the painting, you'd think they'd put some arches on it, that being a famous attribute of the nearby park. But you probably didn't tell Heinzman what to do. You were just grateful you got him. A German-born painter who traveled the world and spoke 8 languages, Heinzman settled in Salt Lake City in the 40s and spent the rest of his years painting the desert.
When he realized it was fruitless and the paint just sank into the sand and you couldn'te tell where he'd even been, he started painting on canvases.
