¥GeoFrame workshop listed priority areas for Flex Array
studies.
¥Cascadia/Idaho bath/Yellowstone/maybe Black Hills
¥Salton Sea/Walker Lane
¥Mid Continent Rift/Superior area
¥S. Appalachians/New Madrid/Reelfoot Rift.
¥These areas will have to get broader community support

tentative choices for MT groups of 70 km sites.
