Crack in the Ground, Fissure vent near Christmas Valley, Oregon, United States.
The narrow volcanic fissure extends two miles through the high desert landscape, reaching depths of 70 feet with temperatures remaining cool even during summer months.
The formation developed approximately 740,000 years ago when cooling volcanic basalt contracted and split, creating this extensive ground fracture in central Oregon.
Geologists and researchers frequently visit this natural laboratory to study volcanic processes and the formation of basaltic fissure systems in the western United States.
Visitors can walk through the entire length of the fissure using established paths, though sturdy shoes and flashlights are necessary for safe exploration.
The temperature inside the fissure remains at 40 degrees Fahrenheit throughout the year, creating a natural cooling system in the desert environment.
