Other Geological Features
A nearby tuff ring has a water-formed cave, called Fort Rock Cave, where in 1936 Luther Cressman from the University of Oregon discovered sagebrush sandals and human artifacts dated approximately 9,000 to 10,000 years ago.
Hole-in-the-Ground and Big Hole are two nearby maars nearly one mile in diameter formed by steam explosion. They resemble impact craters formed by meteorites, but lack the heavy metal signature residues of space objects.
Crack in the Ground and Fossil Lake are two more nearby Ice Age geological features.
South Ice Cave is a lava tube. Derrick's Cave is estimated to be 1,200 feet (370 m) long, perhaps Oregon's third-longest lava tube cave. Devil's Garden Lava Field and East Lava Field are other geological oddities northeast of Fort Rock a few miles. Inflated lava, kīpuka, and lava ponds are found here, plus both ʻaʻā and pāhoehoe flows.
Fort Rock Valley Historical Homestead Museum and the small community of Fort Rock are one mile south of Fort Rock State Natural Area.

Famous quotes containing the words geological and/or features:
“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”
—Ralph Waldo Emerson (1803–1882)
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
