Northwest geologist hot on the trail of Ginkgo lava flow

PO1 William "Chip" Nagel The 1,000-degree centigrade flow was hot enough to stay fluid beneath the crust that formed on the more rapidly cooling surface for a distance of around 300 miles. Finding valleys and other low-lying areas to follow, the Ginkgo forged a path across southern Washington and northern Oregon in an estimated six days.

PO1 William "Chip" Nagel good day Brother William, always informational and of the most interesting. Thanks for sharing, have a blessed day!
