It is titled Desert Ochre, and I love the loose painterly way she has laid on the colour, and how the design draws your eye through the scene.
As well as landscapes, she also paints fly fishing scenes. I am a fly fisher myself, so I appreciate her fly fishing paintings both as art and because they remind me of the sense of peace and joy that I feel out on the river. She posts to her blog, and she also has a website, Mary Maxam Fine Art. Go take look at her wonderful work.
