A unique geological wonder, Crack in the Ground is located 8 miles north of the town of Christmas Valley. A formation of the volcanic origin, two parallel cliffs stretches roughly for 2 miles and reaches up to 70 feet depth at some places. The average width between walls of the cliffs is 10 feet.
Crack in the Ground offers you an adventure hike through the entire length of the crack. Hikers will explore interesting crevices, caves, cracks and formations around every bend along the trail.
The exact time when the formation occurred is unknown, but, according to scientific research, it remains open for about 12,000 years. The fissure formed as a result of the Four Craters Lava Field eruption, which in turn caused sinking of the old rock surface. This event created the amazing monument of tectonic and volcanic activities we can see nowadays.
Often, other fissures are getting filled up by rocks and soil due to the sedimentation and erosion. However, since Crack-in-the-Ground tends to be pretty dry, it doesn't happen to this natural wonder.
The hike is open year-round, but the access might require four-wheel-drive during the winter season. The trail is only open to foot travel, no motorized vehicles, bicycles, or horses are allowed.
Restrooms are available on-site, but there is no drinking water, so make sure you bring plenty of your own. Please be advised to have warm clothes. Even in summer the temperature inside the crack might drop from surface to bottom up to 30 degrees Fahrenheit.
