Hart Mountain Astronomy Site

Hart Mountain


Hart Mountain is a fault-block mountain, in Lake County, Oregon, U.S, which is named for the heart-shaped brand used by the pioneer ranchers Henry C. Wilson and his son-in-law C.G. Alexander. The top of the mountain is part of the Hart Mountain National Antelope Refuge, which hosts pronghorn antelope and bighorn sheep. At the western base of the mountain lies the Warner Wetlands ACEC, a reserve managed by the Bureau of Land Management and home to waterfowl and other wildlife. A trail leads half a mile into the wetlands to a hide.

Activit├ęs in the area and the surrounding refuge include:

  • Wildlife photography and observation are the most popular refuge activities. There are permanent blinds throughout the refuge.
  • Hiking is encouraged, but trails are not maintained, though most of the terrain permits cross-country hiking.
  • Backpacking is the only way to experience remote parts of the refuge.
  • Camping is free, but there are no reservations, and there is a 14-day limit. Generators and power equipment are prohibited.
  • Bicycling is limited to roads open to motor vehicles, but the rough roads require sturdy bikes.
  • Fishing is allowed in a few locations, with an Oregon fishing license.
  • Hunting is permitted for a very limited number of deer, pronghorn and bighorn sheep.
  • Rock collecting is limited to 7 pounds per day, only surface objects may be collected, Digging and blasting are not allowed


It is important to know ahead of time that none of the roads are paved and most are not passable for those in passenger automobiles. There are a few roads that are graded, but most of the roads are dirt ruts, which means that all those who visit should be adequately prepared with a car that can handle these roads. There are no services are available within the refuge, except compressed air, potable water, and a restroom at the refuge’s headquarters.

The nearest fuel and grocery is in Plush, Oregon, which is located 25 miles west, and Frenchglen, Oregon which is 50 miles east. The city of Lakeview, Oregon is 65 miles to the southwest and is the nearest city with basic services such as vehicle repair, lodging, and medical care. Please plan to make sure that fuel is at adequate levels


As Hart Mountain being so far from light pollution and cities, it is one of the darkest places that one can go do astronomy in the state of Oregon. With a plethora of options of places to be outside far away from society and others and light, Hart Mountain is a great place to find options for viewing using a telescope and DSLR photography. However, for astrophotography that requires electrical outlets, the best options would be to go to one of the cabins as there should be electrical outlets.


How far outside of Portland? ~398 miles depending on the route taken. This make the drive around 7 hours and 47 minutes depending on route taken, traffic, and stops.
