Geosonnet 13
Summary:
The rhyolite of Huckleberry Ridge
Discharged a hundred cubic miles yield
The timing of this eruption did bridge
Reversal of the Earth’s magnetic field.
We measure timing of this ancient blast
With argon from potassium decay
This cataclysm from the recent past
might warn us should another come today.
The crystals froze, then thawed, then froze again.
The magma chamber did not slowly stew
