As you hike up the Mossy Cave Trail, notice how the higher elevations of this "canyon" have the lumpy, broken, and random texture typical of Bryce Canyon and its hoodoos. You will also see how the lower section is without hoodoos, and has smooth angled sides looking like a 'V' in cross-section. Because of this little water course, it is unlikely that anymore hoodoos will form here. The existing ones will eventually crumble and Water Canyon will have completed the metamorphosis, becoming a "real canyon."
Take the left fork of the trail up to Mossy Cave. Mossy Cave is not a cavern but a shelter cave. Here depending on the season, you will either see a large overhang filled with moss, or filled with giant icicles. Mossy Cave is a grotto, created by an underground spring.
Take the right fork of the trail and you'll end up above a small waterfall. Here, the rapid trenching of this stream has been delayed by a layer of Dolomite. Dolomite is a special form of limestone that is fortified by magnesium. Dolomite is not only harder than regular limestone, it also can't be dissolved by slightly acidic rainwater. Dolomite is what has created this waterfall and it is also the cap rock for our more famous and durable hoodoos."
