Remnants of the Oregon Trail are seen easily from either end of the park.

Disc Golf at Massacre Rocks

A new disc golf course has been developed and is now open for play at Massacre Rocks State Park. The course is a challenging course and will offer disc golfers a much different golfing experience than the typical disc golf course that is found throughout Idaho. The course is situated in a Juniper, sagebrush area and features narrow fairways, elevation drops and rises and even has several holes that golfers will be throwing over significant ravines to get to the basket. The slogan for this new disc golf course is: “It ain't your momma’s disc golf course”. 

The course is accessed from the parking lot at the fishing access picnic area and the front-nine holes are situated west of the parking lot and the back-nine holes are situated east of the parking lot.

History of Massacre Rocks

Massacre Rocks derived its name from emigrant wagon party skirmish with Indians. Register Rock, located two miles from the park, is home to a huge boulder that holds the signatures of Oregon Trail emigrants who stopped for an evening of rest before continuing on their journey. Today, Register Rock is a beautiful picnic area complete with shade trees, lawn, a horseshoe pitching area, restrooms, fire pits, and barbecue grills.

The park is rich in geological history. Volcanic evidence is everywhere. The Devil's Gate Pass is all that remains of an extinct volcano. The prehistoric Bonneville Flood shaped the landscape of the area, rolling and polishing the huge boulders found throughout the park. The flood was caused when eroding waters broke through Red Rock Pass near the Idaho/Utah border. Lake Bonneville, which covered much of what is today the state of Utah, surged through the pass and along the channel of the Snake River in a few short months. For a time, the flow was four times that of the Amazon River. It was the second largest flood in the geologic history of the world.
