The West gully of Mount Republic is a great way back to Cooke or Silver Gate after a long day shredding Republic bowl, but is also a nice one and done line in itself. It's about 1600 feet long, and is a decently wide, open gut. It usually has snow all the way to the top, but you may have to down climb some scree to get to the snow after warm weather or wind events. To access this line, turn off the Bannock trail at the East end of Silver Gate. Head up the deep creek drainage directly West of Republic. Take the high and East side of the creek, there are a couple tight canyons and waterfalls to avoid. Stay high for about a third of a mile, and you'll be above the cruxes. Keep walking about a 1/4 mile and head east up either side of the gully.
