The following information about the Crack-in-the-Ground is from Wikipedia:
"Crack in the Ground is a volcanic fissure over two miles (3 km) long and up to 70 feet (21 m) deep in central Oregon, US. The eruptions from the Four Craters Lava Field were accompanied by a slight sinking of the older rock surface. This shallow, graben-like sink is about 3 kilometers wide and extends to the south into an old lake basin. Crack-in-the-Ground marks the western edge of this small, volcano-tectonic depression. The crack is the result of a tension fracture along a hingeline produced by the draping of Green Mountain lava flows over the edge of upthrown side of the concealed fault zone. It is located in the southwest corner of Four Craters Lava Field [in the Lakeview district of BLM lands.] Hikers can walk the length of the main crack and explore its tributaries."
The road to the formation is fairly good gravel road, about 4 miles from Christmas Valley on BLM road 6109D. Four-wheel drive is not necessary.
