Searching for a clear window into the cosmos near Ephraim, UT? While enthusiasts often gather at local vantage points for its accessibility, scientific audits conducted by the National Park Service at Observation Point provide the most accurate reading of the regional sky quality, measuring at a Bortle 2.0. Atmospheric stability in the Ephraim region is often influenced by local topography, which can help settle the air for high-magnification viewing.

The Best Times for Stargazing in Ephraim

For the best results in Ephraim, aim for a ‘New Moon’ window. In these dark-sky conditions, the absence of moonlight allows the Milky Way to cast visible shadows.

Expert Tips for Ephraim Observers

Before heading out to local vantage points, we recommend arriving during civil twilight to scout the terrain safely. For the best views here, try to observe targets when they are highest in the sky to minimize atmospheric interference. Local enthusiasts often frequent this spot, making it a great place to meet experienced observers. Regardless of your gear, allow 30 minutes for your eyes to fully dark-adapt.

Observation Point

Goblin Valley SP

21.66 SQM
Bortle Class 2

"An excellent night sky from this location. Moab and Green River barley visible to the E and NE and the Greater Salt Lake City area also just visible to the north. There is some residual haze along the distant horizon from the very hot temperatures. Very good detail in the Milky Way and stars visible down to almost the horizon to the south. Some airglow obvious all around (especially to the west), but otherwise a fairly pristine night sky. No artificial lights from within the park visible from this astronomy site."

Timpooneke Road

Timpanogos Cave NM

20 SQM
Bortle Class 6

"Set up on the ridge line served by Timpooneke Road approximately 1 mile south and 400' above the boundary of the park. This site provides an excellent regional monitoring location that includes views of the Greater Salt Lake City area and the Provo/Orem area. Skies were completely cloud free, but smoke and/or haze was easily visible on the horizon to the NW and SW. The lights of Provo/Orem and Lehi City were directly below and very bright. The lights of Provo/Orem were considerably brighter (cooler blue/white) than those in the Lehi City area. To the east, the skies were fairly dark and the observer was able to see stars to 6.2 magnitude. The Milky Way was visible but not much detail could be seen. The landscape of nearby Mt Timpanogos was completely illuminated by the sky glow and glare from the valley below. SQM reading of 20.33"
