Golden Trout Creek volcanic field
The Golden Trout Creek volcanic field consists of a group of
Quaternary basaltic cinder cones and
lava flows in the Toowa valley of the Sierra Nevada about 25 km (15.5 mi) south of Mount Whitney, California.
Lava flows from the Golden Trout Creek volcanic field erupted through granitic rocks of the Sierra Nevada
batholith during several episodes dating back to about 743,000 years ago, when the Little Whitney
cinder cone and lava flows were erupted. The South Fork cone was erupted about 176,000 years ago and produced the largest
lava flow of the volcanic field, which traveled 10 km (6.2 mi) to the west, possibly as far as the floor of Kern Canyon. Tunnel cone to the north of South Fork (Red Hill) cone is undated, but its lava flow is overlain by glacial deposits and it is thought to be only slightly younger than South Fork cone. The youngest lava flow, from Groundhog cone, is thought to be about 5-10,000 years old (Moore and Lanphere 1983). The lava flow from Groundhog cone traveled 6 km west down Golden Trout Creek on top of the older flow from South Fork cone.
