It's actually three ruins in one. The middle site, which Bloomer calls M-1, contains living quarters. But it's the pictographs that bring the visitors. Room I in the middle of site M-1 is decorated in white, with a crescent moon uncolored on one wall, and a full moon uncolored on the other. Interior of Room I, M-1.
Crescent moon is visible.
Interior of Room I, M-1. Full moon is visible. One thing you won't find much of at Moon House is surface artifacts, such as pottery shards. From the intersection of Utah 261 and Utah 95 west of Blanding, drive about ten miles south on Utah 261. The USGS 7.5' topo maps Cedar Mesa North and Snow Flat Spring Cave may prove useful, although the neither the trail nor the ruin are marked.
