| Bald Knoll is the youngest of a group of basaltic cinder cones on the SW part of the Paunsaugunt Plateau in southern Utah, between the southern end of Bryce Canyon National Park and the western margin of Grand Staircase-Escalante National Monument. The 2135-m-high Bald Knoll has a well-preserved crater and produced a massive youthful-looking lava flow that traveled about 12 km to the SSE. The olivine-basaltic flow fills the floor of Johnson Valley south of Bald Knoll and reaches beyond Ford Pasture into Johnson Canyon. No precise age for the flow is available, but it was estimated to be several hundred to several thousand years old (Gregory, 1951; Davis and Pollock, 2003). Buck Knoll and Black Knoll (also known as Corral Knoll) are cinder cones to the west that lie on the western side of Kanab Creek and produced lava flows that traveled as far as 22 km down the Kanab valley. | |||
