And quite possibly the safest place to hide on End Of Days?
The NCGRP
or National Center for Genetic Resources Preservation where scientists acquire, assess, preserve and provide genetic resources in the form of plant seeds; not as large as the Vavilov collection in Leningrad, but still quite impressive. It is a very secure building as you might have guessed.
The national seed storage vault
is a self-contained section of the building that was constructed to withstand the bombardment of a 2500 pound object traveling at 125 miles per hour and/or whatever floods or perhaps an F5 tornado. Maybe an earthquake too? Or volcanic activity from Yellowstone?
Some seeds on display
but the rest are stored at or near liquid nitrogen temperatures in the vault. The seed storage lab changed its name to the National Center for Genetic Resources Preservation when the mission changed from just storing seeds to preserving all life forms important to US agriculture in 2002.
