Hoodoos, Bisti Badlands
Ref.#00 0465 ~ Hoodoos, Bisti Badlands
- The Bisti Badlands (re-designated the “Bisti-De Na Zin Wilderness) is formed by sedimentary deposits that were pushed up and then eroded away during the last ice age. The surrounding Colorado Plateau was formed in a long period of uplift, rising from sea level to almost 7,000 feet of elevation. When this area was still underground, it was easy for water to find its way through the ashy layers. The water left behind deposits of lime and fine sediment that eventually built up into distributive channel sandstone. Anywhere that water ran atop a layer of ash, it left hard deposits. Subsequent erosion ate away the soft surrounding clay faster, except where it is protected by immediately overlying distributive channel sandstone. The sandstone became the "cap" of a hoodoo of ashy clay. The caps of many of the all-gray hoodoos in the Bisti/De-Na-Zin wilderness result from this process.
