Sunday, May 20 will be a good day for a late summit on Whitney. There will be a partial
solar eclipse that afternoon. Whitney is a bit too far south to see the full annular eclipse (where the sun is still visible as a ring of light around the moon) so maybe a climb of Shasta, instead?
Out here in the flatlands (MO), we'll just get to see the start of the eclipse before sundown but y'all out in CA will get the full benefit.
