There is Astronomy Picture of the Day and Astronomy Sketch of the Day. I'm not sure in terms of sketching if there are enough sketches in Utah, as far as I know I am the only one who sketches and publishes his work (please someone share with me locally). I publish my sketches at a blog I use at a website at http://interstellarsketching.wordpress.com/ and at my blog which is at http://jaysastronomyobservingblog.blogspot.com/ Not sure if I would seek to publish locally as I find Astronomy Sketch of the Day a good medium to publish to if I want to go outside of my normal avenues. I do think you have enough imagers both in and out of SLAS that would publish their work on a local level. However, I know some publish their work over on CloudyNights as well to seek input there.
