Black Butte (formerly Wintoon Butte, Cone Mountain, Sugar Loaf and Muir's Peak[5]) is a cluster of overlapping dacite lava domes in a butte,[2] a satellite cone of Mount Shasta.[6] It is located directly adjacent to the northbound lanes of Interstate 5 at milepost 742 between the cities of Mount Shasta and Weed, California. The I-5 freeway crosses a 3,912 ft (1,192 m) pass, Black Butte Summit, at the western base of the lava domes. The lava domes were extruded at the foot of the cone of Shastina following the period of its major eruptions about 9,000–10,000 years ago.[2]
