Fumarole Butte

Fumarole Butte is a shield volcano in central Juab County, Utah, United States.

The lake was created more than 800,000 years ago by extensive precipitation and glacier melting, and has dried up and re-emerged at least 28 times since.

Made of red and gray material, its composition ranges from dark basalt to reddish scoria.

[4] Fumarole Butte formed during the Jaramillo normal event, approximately one million years ago.

[2] Eruptions from Fumarole Butte created the basaltic Crater Bench Formation, which lies beneath the neck.
