Roche A Cri State Park... a Painting in Purple

This is a painting where I tried something a little different.  I cranked up the purple paint and gave this painting a different slant. 

The Roche-A-Cri State Park in Wisconsin, USA is a rock basically standing up from the ground some several hundred feet. 

The Roche-A-Cri monolith has rock art from the Indians, and even graffitti from the civil war!

I like this painting as I love the color purple, but this painting also shows the rock in a 'different light'.
