This segment of the river features several rapids and obstacles, including the "Devil's Tooth" rapid, a steep and technical Class IV drop, and the "Jaws" rapid, a narrow and rocky channel with multiple obstacles.

The Cedar Creek to Adair Creek segment is managed by the Bureau of Land Management and requires a free permit for all river users. There are regulations in place to protect cultural and natural resources, including a ban on camping within 200 feet of the river and restrictions on fires.

In addition to the Class III+ to IV rapids, this section of the Whitewater River is known for its scenic beauty, with towering rock formations, lush vegetation, and abundant wildlife. It is recommended that only experienced paddlers attempt this run, as the rapids and obstacles can be challenging and potentially dangerous at higher streamflow levels.
