Crack-in-the-ground

Crack-in-the-Ground is an ancient volcanic fissure over 2 mi long and up to 70 ft deep. Normally, fissures like this one are filled with soil and rock by the processes of erosion and sedimentation. However, because it is located in such an arid region, very little filling has occurred and Crack-in-the-Ground exists today nearly as it did shortly after its formation thousands of years ago. An established 2 mi trail along the fissure’s bottom offers a unique hike, where the temperature can be as much as twenty degrees cooler than at the surface.Know Before You Go:Open Season Crack-in-the-Ground is open YEAR ROUND.Trail Difficulty is moderate, with a 70’ elevation gain and sand and rock surface.Universal Access Restroom available.No drinking water available.Trail open to foot travel only.
