Crack-in-the-Ground Loop Trail

Crack-in-the-Ground is a unique volcanic fissure, not a typical gorge formed by water erosion. It resulted from a tension fracture along a hingeline, caused by the draping of Green Mountain lava flows over the edge of an upthrown side of a concealed fault zone. This occurred approximately between 700,000 and 12,000 years ago, following eruptions from the Four Craters Lava Field.

The Crack-in-the-Ground Loop Trail is generally considered a moderate hike. While the main fissure walk involves navigating varied terrain and some scrambling over boulders, it is accessible to most hikers with a reasonable fitness level. However, the additional loop trail mentioned in visitor tips can be more challenging, requiring significant scrambling over large boulders and is less traveled. Beginners should be prepared for uneven surfaces and occasional narrow passages.

While the exact duration can vary based on individual pace and how much exploration you do, hikers typically spend 2 to 3 hours completing the main Crack-in-the-Ground Loop Trail. This allows ample time to navigate the fissure, explore its unique features, and enjoy the cooler temperatures within.

Yes, the Crack-in-the-Ground Loop Trail can be a fantastic and memorable experience for families. However, parents should be aware that the trail involves scrambling over boulders and navigating uneven, sometimes narrow, terrain. It's best suited for children who are comfortable with light climbing and have good balance. Younger children might need assistance in certain sections. The unique environment and cooler temperatures often captivate kids.

Yes, dogs are generally allowed on the Crack-in-the-Ground Loop Trail. However, due to the challenging terrain, including scrambling over boulders and potentially narrow passages, it's important to consider your dog's agility and comfort level. Always keep your dog on a leash and be prepared to carry water for them, especially during warmer months.

There is a designated parking area at the trailhead for Crack-in-the-Ground. No permits are currently required to hike the trail or park. However, access roads are unpaved and can be rugged, with four-wheel-drive vehicles often recommended, especially during wet conditions. Parking can fill up quickly during peak seasons, so arriving earlier in the day is advisable.

Even in summer, the temperature inside the crack can be significantly cooler (up to 20-30°F or 10-15°C colder) than the surface. Therefore, it's wise to wear layers. Sturdy, closed-toe hiking shoes with good ankle support are essential due to the uneven terrain and scrambling. A headlamp or flashlight is also highly recommended for exploring deeper, darker sections. Don't forget water, snacks, and sun protection for the exposed sections of the trail.

Yes, Crack-in-the-Ground is open year-round, and winter hiking is possible. However, conditions can be significantly different. While the crack itself might offer some shelter from wind, the surrounding area can experience snow and ice. Deeper sections of the fissure are known to retain ice well into spring, so expect potentially slippery surfaces. Appropriate winter gear, including traction devices for your boots, is highly recommended. Access roads may also be more challenging due to snow or mud.

Inside Crack-in-the-Ground, you'll encounter fascinating crevices, small caves, and intriguing rock formations composed of volcanic fissures and tuff rings. The walls are rough and irregular, showcasing the basalt rock. The dramatic temperature drop and the slot canyon-like atmosphere are also key features. In deeper, darker sections, you might even find ice persisting well into spring, a testament to the fissure's unique microclimate.
